Fashion Week didn’t slow down for the weekend, but don’t fret—we took notes! Tommy Hilfiger celebrated his 25 anniversary in the biz, with stars like Jennifer Lopez and Bradley Cooper sitting front row at his show and rocking out to a special performance by The Strokes at the after-party. Beyonce debuted Tom Ford’s new women’s collection (his first in 6 years!) in a super-secret presentation that was masked as a cocktail party on the calendar. Click through the gallery below for all the need-to-know news, trends we are loving now, plus our take on the hottest moments from New York Fashion Week!
