People complain that fashion month is exhausting because they have to travel to multiple cities and drive around to dozens of shows and appointments all day. But the real reason it’s so tiring is the parties. Getting dressed, shod, and coiffed for these shindigs is a day’s work in itself. Then, once you arrive, there’s the posing, the dancing, the making conversation with people whose names you can’t quite remember, and, if you’re feeling naughty, the drinking and late bedtimes. But many fashion people are just genetically built for these activities, some exceptionally so (although their stamina might have something to do with being under 25). We’ve rounded up this season’s most admirable partiers; journey with us through their antics in this slideshow.
