It may be stilettos at dawn to get a ringside seat at New York's most exclusive fashion shows, but forget the fur-clad heiresses: today's VIP is the internet.
The explosion of social media is perhaps the greatest revolution in fashion since Mary Quant's mini skirt, transforming the industry's branding and fan base.
And that revolution is on display like never before at New York Fashion Week.
"It's been incredible, absolutely incredible. Social media has made such a difference," says Lubov Azria, chief creative officer of fashion house BCBG Max Azria Group.
The front-row presence of Vogue supremo Anna Wintour may remain the important accolade for any designer, but Twitter and bloggers are chipping away at the monopoly of magazines.
"It used to be where the editors would come in, whether they liked the collection or not, they would have a certain point of view, and that's what everyone saw," says Azria.
"Now with social media, we have a voice. We have a way to express what we feel, why we feel certain things. It's incredible."
As a result, BCBG's typical client, the socialite "who dances and dines", has changed slightly.
"I think it brought a younger crowd and it also brought the crowd that perhaps never knew this or this about the brand. It brings awareness," says the Ukrainian-born designer.
Fashion houses all have websites, many offering e-commerce, as well as Twitter, Facebook and Instagram accounts.
Runway shows are now streamed live online, attracting an audience of millions across the planet.
But Marc Jacobs, who recently stepped down from his post at Louis Vuitton to concentrate on his own brand, has become the talk of the town by trading not in dollars but in social media currency.
At the Daisy Marc Jacobs Tweet Shop, fans and fashionistas collect a free perfume sample for every Instagram, tweet or any other post that includes the hashtag #MJDaisyChain.
The more creative the posts, the better the prizes. And at the end of the week, the winner gets a Marc Jacobs handbag.
Tommy Hilfiger, another US fashion house giant, says its social media channels provide "personalised access" to millions of fans and consumers.
Twenty local Instagramers were invited to the label's catwalk show on Monday, one of the biggest of Fashion Week, and given backstage access to record what happens live.
Long gone, Hilfiger said, are the days when it took six months for the catwalk shows to reach the consumer.
"Our digital initiatives underscore the differences between how runway shows used to be done and how they are organised today," Hilfiger says.
Backstage vignettes offer an intimate look at a part of the show previously the preserve only of models.
Rebecca Minkoff, the New York designer who initially made a reputation for producing luxury yet affordable handbags, joined video-sharing app Keek specifically for Fashion Week.
The site allows users to post videos of up to 36 seconds. One shows the arrival, in the freezing cold, backstage. In another, TV actress AnnaSophia Robb picks out an outfit.
Then there is wearable tech.
Alexander Wang, arguably the biggest draw of the week, unveiled an androgynous futurist show in a Brooklyn warehouse that featured 3D and heat-activated fabric.
BCBG Max Azria also has "Epiphany Eyewear", its answer to Google Glasses, which are equipped with HD video, and sent down the runway on models.
Victoria Beckham, who has wowed the fashion world since making her sophisticated, elegant debut in 2008, has collaborated with Skype in a special Fashion Week project.
The collection of videos, audio clips, Twitter and video interactions highlighted her social media credentials, all the more vital given her previous outsider status.
The male voiceover says social media has forced "a 21st century fashion revolution".
"Once you know the story behind anything, it's more compelling. You can connect with it. May be that's what we're doing," adds a member of her team.
