good evening, and thanks so

much for joining us. once again, the world is watching as california are consumed by flames. it is a harrowing battle between man and nature. and we are on the scenes with the men and women leading the charge. here's matt gutman. >> reporter: if there was something they could do with that wind. we're going to the other side of the car. seek shelter. you can see the embers cast right there. this is the easy fire in simi valley, california, north of los angeles. it's a new fire that broke out early this morning, fueled by the strongest santa ana wind event in over a decade. gusting at over 80 miles per hour it tripled in size in just two hours. the winds make targeting the fires from the air extremely difficult. right now we're about to get dropped on. you can hear that plane coming through. look out! it's going to hit.

>> reporter: winds are powerful enough to knock over big rigs. and can carry embers that can start new fires miles away. and you can see how fast this wind is moving, just picking the smoke up and whisking it right off the ground here. the heat is intense. the wind is enormous, and it's fueling that inferno. it moved so fast we had to take cover behind a fire truck. oh, my god, you can see that wind. the national weather service has issued what is called an extreme red flag warning, something that it has never done before. these santa ana winds form when strong high pressure over the rocky mountains pushes cold, dr. and, when it moves through the mountains and canyons in southern california, it compresses and heats up, super charging the wind speeds. the so-called easy fire came within 30 yards of the presidential library.

that's where firefighters were able to create a buffer zone of brush. david muir was there on the front lines. >> this fire has been moving very quickly. it broke out in the middle of the night here in simi valley. they're trying to protect about 6500 homes now in danger. at least 1300 acres are already burning, and of course part of the overall effort, the effort to protect the reagan presidential library. >> reporter: and inside the library, air force one. smoke and fir fir fir fir the opposite side of those windows. >> it's the largest presidential library in the u.s. national treasures here. >> reporter: what is it like seeing it so threatened? >> scary situation. you don't often come to work to see a disaster of this magnitude. and we're surrounded by heroes,

firemen with shovels and rakes. up in the air. they're doing a heroic job. they're going to save this library. >> reporter: it's been a relentless battle. airplanes and helicopters dropping fire retardant throughout the day, dowsing flames. the sheriff's office posted this photo to instagram, showing deputies covered in pink retardant. >> you can see the urgent effort in the hills because of the santa ana winds. they are flying overhead. we have wind gusts up to 60, 70 piles per ho miles per hour already, and you can see them dropping retardant. >> reporter: across the fire zone, folks scrambling to get to safety. >> you can tell how fast this fire is moving. it's just cooking that grass. that's raw fuel for a fire like this. it has been moving with the wind, casting that massive column of smoke here, obviously

clogging up this road, but there's nothing that's going to stop this grass fire at least right now. these have completely burned through at this point. that's how fast this thing is moving. >> reporter: along this road, coy hear the whinnying of horses through that haze of smoke. you can hear horses in there, but it's hard to tell. [ screaming ] where are you? >> here, here! i'm trying. >> reporter: a woman alone fighting the flames with that garden hose. you're okay. so sorry. >> yeah! >> reporter: suddenly, she's called to the stables. >> i got to get my >> reporter: her name is ariana shulkin. >> i'm coming, girl.

>> reporter: and the wind and smoke spooking her horse, athena. >> we need trailers! >> reporter: other animals with their owners. finally, athena is loaded in like so many other horses and driven to safety. >> i know there are still horses. a lot of owners haven't been able to get out yet. >> reporter: and east of l.a., the hill fire also erupting today. patients and seniors evacuated outside this senior living home, wearing face masks to shield them from all of the smoke in the air. holding hands as workers desperately try to wheel them out to safety. some still in their beds. and, in los angeles, the getty fire had threatened the getty museum and its priceless art collection. that fire now under control. yet firefighters across the state are working around the clock tonight.

station number nine has been battling the flames for days now. their first shift, 26 hours straight. they haven't been home since sunday. >> this was a part of los angeles that hasn't seen fires in quite a few years. >> right. i don't think this area's seen fires since i believe it was 1961 with the bel-air fire. but i mean something that residents here, it's a new reality. >> reporter: the firefighters keenly aware they are facing something new with these violent santa ana winds. >> we haven't seen something like this since 2007. so just to give you an idea of how unusual it is, it's been 12, 13 years since we've seen such a strong wind event. >> that red flag warning hasn't been issued since 2007, what does that say to you? >> that the wind is so high and so fast that it's going to be wind driven. >> reporter: despite the challenges and danger, the dedication to the people and homes they are fighting for remains. >> we try to save them all.

like, we can't always be in the right place at the right time. and we do the best with what we've got. >> which explains why you can have a home standing here and the one behind us gone. >> absolutely. some of it's timing and some of it's what we can't account for when the fire generates its own weather. >> i know you wish you could save them all. >> if we could. >> reporter: tonight the winds have calmed down, but more red flag warnings are expected tomorrow as the state of california remains on edge, and its heroes continue to hold the line. >> our thanks to matt and david on the ground, and our thoughts are certainly with the brave first responders and families affected. up next, the lingerie company turning out things for the hottest holiday of the year. plaque psoriasis. e now, there's skyrizi. 3 out of 4 people achieved 90% clearer skin at 4 months after just 2 doses. skyrizi may increase your risk of infections and lower your ability to fight them.

this halloween, it seems nothing is off limits for one lingerie company as they create spins on classic costumes and pop culture. some wondering whether it's feminism or just too much. >> give me some attitude. >> reporter: it's the sexiest holiday of the year, but dressing up on halloween has come a long way since "thriller." ♪ because this is thriller >> reporter: the costumes have become sexier, and sexy costumes have taken on a life of their own, morphing from classic looks like the s.w.a.t. hottie and

angel, to tongue-in-cheek and topical, like fake news. >> we get a lot of inspiration from, you know, girls in the office, they're drinking white claw. >> reporter: these days nothing is off limits, even childhood friends like mr. rogers. ♪ please won't you be my neighbor ♪ >> reporter: isn't mr. rogers sexy enough? >> he is, why not bring him to life a little more. >> reporter: she is the vp of merchandising at yandy. every year they generate thousands of costumes and tweets. >> make sure you go out there wearing what you want. sexy mr. rogers is just one that has gone viral already. you seem to do this every year. do you laugh? >> you have a giggle at it. >> reporter: based on the headlines, it seems a lot of

people had a giggle at that one. >> he's the nicest neighbor in town. i grew up with mr. rogers. to do this is an honor and a lighthearted costume. >> reporter: not everyone is laughing. the company has courted plenty of controversy, too. last year, their sexy red red rd was pulled from shelves. why pull that? >> it wasn't what we wanted our season to be focussed on. again, this is a fun time. let's not make it a darker time. have fun. that's all this is. that's all halloween is, a day to escape in and have a blast. >> reporter: and, at yandy, it's clear they are having a blast. how much fun do you have coming up with these ideas? >> we always say this. if someone was listening to the conversations i'm having with the factory, like this crest does not look right. this is ridiculous. they're very, very kind of ridiculous kind of conversations, but very serious

to us. first of all, this is a 365-day-a-year business for us. we're thinking of halloween for a year. >> reporter: a year. so november 1st you get started. >> yep, we're always watching the news cycle. we're always kind of taking a look at what we could spin. we have a running dock in the office that is open to everybody to add ideas, everybody from warehouse to hr is always giving us ideas. some of the husbands and wives at yandy are always giving us ideas. we pull from a pool i'd say. >> reporter: not every idea has what it takes to be a hit. what are some memorable ones that ended up on the cutting floor. >> we had elizabeth holmes. fat thor. >> you could probably pull that one off at home. wig, red lipstick and a dress. >> reporter: it's a never-ending process. while we visited offices in phoenix, arizona, just weeks before halloween, kylie jenner's

rise and shine video went viral. the women at yandy went to work. >> this shall be the three pieces that we need to create the rise and shine. >> reporter: other recent adds to the 2019 collection include "ms. impeachment", and that sold-out chicken sandwich. >> sometimes we're like straight to the drawing board. we are design costumes for women. the majority of us are women here, so we're having fun. it's a laugh. >> i mean, sexy bob ross, i think she had all the elements there to be sexy. we just made the shorts for his jeans really, really, really short and added the palette, and everything like that. i think we nailed it. >> reporter: you taught me something about the bob ross costume. thorts. >> when they're so short they could be a thong, they're

thorts. >> reporter: you can always go with actual thongs, like the kardashians last year, dressed as victoria's secret angels on their show. >> i would describe it as something that's been going on for at least 20 years but has gotten to the extremena t in th last five. used to be just the people at the party would see the outfit, now you're posting it to thousands of followers. >> halloween is the one day a year where a girl can dress like a total slut and nobody can say anything about it. >> i'm a mouse, duh. >> reporter: and "sex in the city." >> witch and sexy kitten. >> reporter: and beloved by millions. those who argue it's feminist and those who say it's not. >> a true feminist just does what see wants to do. i think people should embrace it and have fun. >> reporter: believe it or not, there's even a study on the

subject. professors from west chester university have followed the phenomenon closely. what made you want to study halloween costumes? >> you can see some of the most potent examples of gender roles when you look at holidays. i've had students say are you aware what's going on in adult costumes? >> part of the interest was there. >> reporter: the professors and students studied 1600 costumes and found over 90% of women's costumes were sexualized. >> i had my students one semester go online and see how many costumes they had to look at before they could find a costume that wasn't sexualizing or objectifying. they had to go to 50, 120. for the boys, you looked at the first one. >> reporter: you're saying this isn't about women wearing what they want, they're not given any other options. >> sexual agency is powerful and empowering for many people, and i think it's really important for us to stop making appearance

comments and shaming folks for the way that they dress. but the purpose of our research is not about restricting options. it's about expanding them. and i think also thinking about our definition of what sexy is. >> reporter: yandy offers plenty of objections that are more full coverage, with over 1,000 plus-sized options. one of the arguments we've heard are there aren't enough options for women who don't want to dress in a revealing manner. >> we're telling all the girls out there to own your sexy. everything from floor length to ball gown to thorts, we've got you girl. i'm not comfort nable in a thor. but many people are. >> reporter: it's a moving market. >> we've done over 120,000 halloween orders to date so far this year. >> these are safe for work costumes. this is a nice pumpkin tee shirt dress. >> reporter: you can never have

too many sexy tops apparently. >> no. >> reporter: what are some of your most popular costumes? >> our s.w.a.t. hottie. still need the tried and trues, s.w.a.t. hotties, day after day. >> reporter: what would the world do without s.w.a.t. hotties. >> we want to you have fun that day. all controversy aside, enjoy it. >> reporter: even the professors can't argue with that. >> i love halloween. >> you and me both. >> it's my favorite. one of the things that's also happening is there are movements, i mean, i hear the word body positivity movement. that's empowering. if it's an opportunity to feel sexy, i think embracing that is awesome. >> happy halloween! >> reporter: for "nightline," i'm diane macedo in phoenix. >> and ourort. next, kevin hart on t mend. his message of thanks after a terrifying accident. y, raj, and.
