Oh my. We are absolutely head over heels for this show-stopping, jaw-dropping, deliciously naughty ouvert bottom. This stunner's bikini silhouette is totally, gloriously open in the back, with the bold, slender straps perfectly framing the bum. A delicately flirty cascade of tulle ruffles at the hips, ruched trim, and a sheer mesh body all combine to make this our go-to boudoir favorite. A piece this dangerously gorgeous is always in season.
