Social media fuels 21st century fashion revolution

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,” their answer to Google Glasses that 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.
