We almost didn't want to tell you, this was so good. Next Wednesday, March 18, from 10 a.m to 5 p.m, over 400 pieces from the storied French house will go on massive sale—we're talking 70% off or more. That means dresses starting at $325 (versus $1,500) and coats starting at $560 (versus $4,000). We can't remember the last time Lanvin had a sample sale, which means we've just hit shopping nirvana. It's guaranteed to be a madhouse scene, though, considering the sale's only for one day, but we're planning on camping out with our most fashionable sleeping bags. See you there. Wednesday, March 18, 230 Fifth Ave. (between 26th & 27th St.), (212)-920-1211.UPDATE! Lanvin press offices just told us that the sale is not affiliated with the company, and that it's "all very suspicious." This means that either this sample sale is indeed a mirage, or that something fishy is up. Depending on how badly you want a triple-digit Lanvin piece, guess we'll see you on Wednesday at the scene...
