Yes, Francophile, you read that right. This 'ouvert' from Britain's Lascivious brand is downright sexy in only the way that an, ahem, open bottom can be. The sophisticated shape features a traditional bikini silhouette with a strategically-placed cascade of gorgeous lace (!) opening up to that ouvert back and bottom- framing the bum just so. We might have told you how much we love this open back with its decadent lace, but, frankly, in a piece like this we can't say much of anything at all. Trust us, speechless is a good thing.
