"Periscope is changing the way fashion fans consume and experience fashion, essentially democratizing it for everyone," says Rachel Dodes, head of fashion partnerships at Twitter Inc . "The two-way nature of Periscope allows people to engage in a way that wasn't possible before, and as we've seen this fashion week, the community is embracing it."
Through the last day of the fashion event, there were 97 Periscope livestreams coming from designers, according to Socialbakers, a social media marketing consultant.
The goal for attracting buyers? "Making them feel like they're at the show, just like I'm at the show," says Jaclyn Jones, an editor at fashion trend forecasting firm WGSN.
Designers make it easy for millennials to tap into social media for instant feedback. Almost 70 percent of millennials check in with peers on social media before making a purchase, according to strategic retail advisory firm HRC Advisory.
Social media sites like Instagram, Facebook and Pinterest all play a role in getting the thumbs up. To make sure customers can connect at the point of sale, retailers are installing Wi-Fi and charging stations in their stores, says HRC Advisory's Chief Operating Officer Farla Efros.
That will keep millennials browsing -- and buying -- in style.
