this is "nightline." >> tonight, big little styles. from the emmys to back to school fashion, the stylists now taking on new pint-size clients. chic kids reaching for the stars by reaching for the latest looks at retailers. like rent the runway. >> try on your new outfits for school. >> the surprising fashion industry trend that has the youngest fashion northeastas hoping to feel good by looking fabulous. bob iger the disney media titan behind some of the most stunning deals of the century. revealing in his new book his childhood hurdles. and the bold new move into streaming with disney plus. >> i mean, how many streaming services is a person going to pay for? and call for change.

the front row seat and the teen storming the united nations with her impassioned speech on climate change. >> we will never forgive you. >> but first the "nightline" 5. they took $12.8 billion from big tobacco. juul marketed mango, mint, and menthol flavors, addicting kids to nicotine. five million kids now using e-cigarettes. the fda said juul ignored the law with

misleading health claims. now juul is pushing prop c, to overturn san francisco's e-cigarette protections. say no to juul, no to big tobacco, no to prop c. good evening.

thanks for joining us. red carpet season is already under way, but hollywood stylists are also helping kids starting the school year with their best foot forward. now inside the surge in young clients looking to splurge for the perfect look. >> reporter: red carpets, like last night's at the emmys, are the super bowl of the fashion world. stylists like law roach, who dressed zendaya pulling out all the stops for that perfect picture. while this new york boutique is a long way from hollywood, during this mother-daughter shopping spree, there's an unexpected a-list perk. >> what do you think of these? >> i like that. >> reporter: 9-year-old riley robinson is about to meet with her personal stylist. >> try on your new outfits for school. okay, we'll be right back. >> she's an actress right now in new york and so we're looking for audition clothes and i had no clue. >> reporter: meet mona sharaf, a fashion consultant with pint-sized clients. >> my first few years, i didn't really see many kids or any

kids, and then, all of a sudden, my phone was blowing up with kids themselves calling me their parents calling me. >> reporter: at hundreds of dollars an hour, styling used to be a service exclusive to the stars and the uber wealthy. celebrity stylists like rachel zoe even becoming household names. lehose s. ror parents like t a prof >> a lot of times, i would get online and try to do this for myself before i found mona, and i would spend a lot of money because we would order things online that weren't the right size and didn't look right. we'd have a whole closet full of clothes that we couldn't use. >> i'm really excited. and i just love her outfits. >> reporter: kids' fashion is a gigantic industry, and the landscape is changing. many big name box stores have shuttered their doors and alternative retailers are rushing to fill the void. >> all of these old school retailers that have been around for years like gymboree and the

children's place are closing or going bankrupt. meantime, you have all of these new players which are known as digital first. they started out only on the internet. you could only access them through apps and websites. they're now actually building out storefronts. but because of instagram, because of where millennials are with their spending, a lot of these digital first brands are doing quite well. >> reporter: despite the troubles some mall chains face, the luxury market for children is booming. in the past three years, couture labels like givenchy and balenciaga have joined the kids' table, alongside top labels like gucci and stella mccartney that have long had children's lines. >> of all the children's clothing businesses, luxury is one of the groups that's growing the fastest. overall, children's clothing does about $233 billion in sales annually. the luxury market does about $6 billion and it's growing even faster. >> i feel like it's just this trend now that blew up.

>> reporter: were you surprised by how much your phone blew up? were you surprised by the demand? >> i was shocked. i was shocked. i never marketed to this group of kids because you know their sizes change. how long are they wearing it? not long. so is it worth it to pay my fee to pay for all these clothes when they're going to grow out of it so soon? >> reporter: mona has been in the fashion industry for six years, and only recently started taking on what she calls her "little clients." she estimates that 20% of her business is now children and teens. >> my first clients it's a great story, it's a 10-year-old boy. his mother called me and said i need you to help me make my son dress younger. and i'm like, younger? he's 10. she's like, "yes, my son likes to wear suits and like suits to school." >> reporter: she says it was a surprising request. >> i geared him towards more casual looks. at ten, they already have their own personality and their own

style figured out. so i only got as far as i could. >> reporter: a personal stylist for a child or teen is an extravagant cost. mona charges around $200 an hour per session. but she argues her services do make financial sense. >> we wear 20 percent of our closet 80 percent of the time, so that's true for kids. you're saving a lot of mistakes. so yes, it does save money. >> reporter: and she says the confidence the right wardrobe can inspire is priceless. >> reporter: i would imagine that people watching on tv would think why on earth do kids need a stylist. and it's a fair question. >> i say it's -- it's a different world. kids make their own decisions. they're well-informed and they want that same confidence an adult has. and their wardrobe is a stepping stone to that. when you're confident with how you look, everything else becomes so much easier like their posture changes.

it's amazing. >> reporter: like for andrew lilly, who went shopping with mona for his first year of college. >> oh, wow. you look really nice. let's give you two different jackets. >> my mom offered it, she suggested it. and i kind of wanted to get a new look, so to say, not quite roll oust bed but something more like pride in my appearance. >> the thing about millennials, that they're wait longer and they're having fewer kids, which in many cases means they have more disposable income. they also have phones in their hands. that keeping up with the joneses on instagram is actually driving a lot of these retail firms. they can get that great picture and post it on instagram. >> reporter: retail startup rent the runway has also jumped into the high end kids clothing market, expanding to include posh picks for the playground set. >> we're actually seeing such positive traction in our kids business. because they're constantly growing.

to be able to rent an item that your child will only wear once or twice is actually smart and sustainable as well. >> reporter: rent the runway charges $89 to $159 per month for its childrens' service, which lets parents and kids borrow four items at a time. >> girls want variety. so our customers wants fun variety and freedom in her wardrobe just like her mother does when she uses rent the runway. >> rent the runway definitely was a trailblazer, and now that millennials and gen z are getting more comfortable with this idea of renting, when you think about being a mom or dad of a young kid, renting that clothing for them makes a lot of sense at the right price point. >> reporter: more budget-friendly options are also available. walmart now offering a kid-friendly subscription service. four or five curated items shipped by about 50 bucks a box. while some parents will choose practical wash and wear over oat couture, the youngest fashionistas are clearly helping

reshape the way of shopping. >> kids now are different than kids in the past. they're armed with information. kids don't listen to parents the way they used to. and that's my big takeaway from this. parents love me because there's less fighting over things like clothes. up next, the man behind the disney empire. his plans just might transform how we watch our favorite shows. we call it the mother standard of care. it's how we bring real hope to our cancer patients- like viola. when she was diagnosed with breast cancer, her team at ctca created a personalized care plan that treated her cancer and strengthened her spirit. so viola could focus on her future. their future. this is how we inspire hope. this is how we heal. cancer treatment centers of america. appointments available now. cancer treatment centers of america. ♪upbeat musieverything was so fresh in the beginning.

♪ from "let it go" to "wakanda forever," he's helped usher in

some of the most iconic stories in hollywood. but it was bob iger's childhood hardships that helped catapult him to the head of disney. now how his latest venture just might redefine the way we watch entertainment. >> we're going in here? yeah, this control room is different than it used to be. >> reporter: bob iger runs the $239 billion disney media empire, and right now he's feeling nostalgic. >> i saw howard cosell interview muhammad ali in this studio. >> reporter: everyone remembers their first break. >> they used to call me bobby. so anyone who calls me bobby on 66th street, they worked with me a long time ago. >> reporter: and iger's was here at abc 45 years ago as a studio supervisor, making 150 bucks a week. >> i remember people saying to me, "you're going places." i'd think, "what -- what do they know?" i did not have a particularly unique background, intelligence,

but i worked hard. and in some cases i could outwork everybody else. >> reporter: his legendary work ethic, including his 4:00 am workouts, helped him transform disney, abc's parent company. ushering in massive hits like "the lion king," "frozen," and "avengers: endgame." the company's net income has increased more than 400 percent since he took over in 2005. in his new memoir "the ride of a lifetime," iger chronicles the core values that helped him triumph through decades of corporate jujitsu, including eye-popping multi-billion-dollar deals like the latest with 21st century fox. you have an entire chapter about "innovate or die." which sounds a little darwinian. >> yeah, it does. >> reporter: who survives in this survival of the fittest? >> well, i think it begins with being bold. this world today is so unpredictable and moving so fast. baby steps don't work. >> reporter: perhaps his boldest move yet, launching disney plus this november, which means pulling blockbusters like the avengers and star wars off other streaming services. >> reporter: you're taking

losses on the licensing fees side in order to assure the future. is disney late to the game? and -- and how do you take on netflix? >> well, we're not late to the game because the game's still going on. and we're not really taking on netflix. we're bringing disney out. and the disney includes disney and pixar and marvel and star wars. and national geographic. >> reporter: and yet, when people look at their monthly bills, how many streaming services is a person going to pay for? >> well, i think there's room for people to buy multiple services. and i think they will. we're entering a very, very robust marketplace. >> reporter: it's a media marketplace iger has mastered over decades, but first, he had to ditch this dream. >> good evening, i'm bob iger. >> you started as a weatherman. >> yes. >> reporter: i managed to dig up this fabulous photo of you from cable channel 2. >> in ithaca, new york, yes. >> reporter: evening news in ithaca, new york. >> that's a sorry picture. >> reporter: why did you cut your on-air career short? >> i wasn't that good at it, which is something i discovered relatively early on. and i just didn't think i'd end up in a role that would be

fulfilling enough. i wasn't good enough. >> reporter: it wasn't long before the kid from middle class long island, whose father suffered from mental illness, found himself working at abc sports. >> how do you think navigating your dad's moods helped you deal with crises of personalities later in life? >> manic depression is an illness. and there was a lot of unpredictability at home. never -- any time that i felt endangered in any way. but was clearly aware of him being in a very, very dark place. i think managing people starts with the ability to put yourself in their shoes and be empathetic. >> that ability served iger well, rising to the top of abc entertainment, greenlighting edgy shows like "nypd blue." >> a-ten hut. >> reporter: and "twin peaks." >> my log saw something that night. >> reporter: doubling down on creativity, iger saved disney's ailing animation division by acquiring pixar. but first, he had to woo steve jobs.

>> reporter: how did you get him to trust you with pixar and this creative brand that he'd helped build? >> he must have just seen in me something that he liked and was different, i don't know. >> new toys! >> he trusted that pixar would be in good hands at disney. he used to say that the intersection of liberal arts and technology made his heart sing. >> reporter: their friendship helped smooth the way for iger to make acquisitions many thought were impossible, like george lucas's namesake lucasfilms. >> there was a trust, which i was so grateful for. i respect him enormously. >> reporter: and marvel's universe of characters, paving the way for disney's most daring movie yet. >> wakanda forever! >> reporter: in the book, you talk about the "black panther" premiere as being one of your proudest achievements. >> there are, you know, a very handful of days that i will remember for the rest of my life. i knew that we had something really special here. not just as a quality film and story, but something that actually could change the world. there was skepticism about a

movie like that, particularly with a predominantly black cast, resonating around the world. and yet it did. >> reporter: why do you think it took hollywood so long to embrace main characters of color? >> i think too many people rely on history and experience. it's much more exhilarating and much more important to believe what you believe is right and actually follow those instincts, follow your heart and your gut. >> reporter: iger's instincts have propelled him from humble beginnings to corporate titan, earning nearly $66 million this year. >> reporter: ceos are often criticized for this pay gap between executives and -- and worker bees so to speak. >> we obviously have to care deeply about our employees, because it all starts from them. they create the value for the company and for the customer. you know, there are over 200,000 disney cast members or employees around the world. we've created tens of thousands of jobs in the u.s. we've created a lot of opportunity for the people who work for us. and -- and we also compensate

them well in the form of just annual compensation and other benefits. >> reporter: but when employees cross the line, like pixar's famed chief john lasseter, iger has dealt with them swiftly. >> reporter: the me too movement was a seismic sort of event in the media world. it swept up a lot of executives, including john lasseter. how did you deal with it from a management perspective? >> well, i think the first thing is not being in denial. accepting the fact that there is a problem. recognizing that it was time for considerable and -- change, almost on an emergency basis. >> reporter: i was actually quite shocked to read about the incident that occurred when you were starting out in television. it was an illustration that sexual harassment is not about sex. it's about power. >> i was a very low-level production person on the evening news. and i had to go into a control room to ask whether we had to shoot parts of the show again, and there was a producer. i think i asked him, "how does it look?" and he unzipped his pants, "you

tell me how it looks." i can chuckle about it a bit. there's nothing funny about it, at all. but it is telling in the sense that if that could happen to me, you know -- that it has happened way too often. and you have to create an environment where that -- it is thoroughly, thoroughly unacceptable to behave that way. >> reporter: integrity, says iger, is his touchstone. the 68-year-old plans to retire in 2021. his closest confidant, wife willow bay, mom o'tto two of hi four kids. in "toy story 3" when andy goes off to college i went. >> i have four kids. three of them have gone off to college. and i'd say in all three occasions i, you know, had tears in my eyes. there's a shot that is over the shoulders of buzz and woody. so it was from their perspective, seeing andy drive away. and it was, you know, that parting -- >> so long, partner.

>> of this loving close relationship that just touches your heart. leaving a company with this legacy and with this role in good hands, in a good place is what i want my legacy to be. and to just bring the world happiness and entertainment and a sense of well-being that i think it truly needs. >> proceeds from bob iger's book will fund diversity at journalism schools across the country. up next, my question to the teen grabbing the world's headlines today with her fierce plea to stop climate change. performance comes in lots of flavors. there's the amped-up, over-tuned, feeding-frenzy-of sheet-metal-kind. and then there's performance that just leaves you feeling better as a result.
