New York Fashion Week Fall 2016

The biggest trend at New York Fashion Week had nothing to do with the hottest fabric or the latest "it" bag. Instead, it was the idea that even the most fashionable industry could be in need of makeover.

In an effort to appease digital-savvy consumers, who crave instant gratification for their favorite runway looks, designers including Rebecca Minkoff, Michael Kors and Lela Rose offered shoppers the chance to purchase some or all of their favorite pieces immediately following their romp down the catwalk.

"This is the wave of how brands … are moving," celebrity designer LaQuan Smith said at his Sunday presentation, during which showgoers could purchase six of his pieces straight from an iPad. "I definitely want to be at the forefront of that."

Not everyone is sold on the idea. Designer Nicole Miller said she is "totally against" changing the fashion calendar to show collections closer to the season in which they'll be sold. She said it would remove a lot of the creativity from the design process, and shift all of the attention to sales.

"Today I would be showing my spring collection, which I made in September," the designer said backstage Friday. "We'd all be kind of bored with it, and it would be edited to just the best sellers at this point [because] the buyers would have already seen everything in the showroom."
