Who is Tomo Koizumi? Good question. It's been a question on the lips of every editor since seeing his couture-like Loofah cocktail dresses in the basement of the uptown Marc Jacobs store last Friday evening. New York Fashion Week got off to a fairly relaxing start with Tom Ford, which heralded the return of '00s supermodel Caroline Trentini to the runway, and then came the tulle. It was W's Contributing Fashion Creative Director Katie Grand who found Koizumi on Instagram. The Japanese designer, with Grand's help, created quite a splash with Rowan Blanchard opening the show, Bella Hadid walking, and a creative team any emerging designer would die for (Pat McGrath, Guido Palau), and everyone from VIPs to assistants crammed into the nooks and crannies of the store's basement to catch a glimpse of Koizumi's beautifully constructed rainbow tulle. It's not too much to say his show was the talk of the town—and we were not even halfway through NYFW. With favorite labels Brandon Maxwell and Proenza Schouler, as well as upstarts Area and Vaquera, still to come, there was a plethora of both chic and boundary-pushing looks to take in throughout the rest of New York Fashion Week. Now, at its conclusion, we've rounded up some of our favorites.
