You know a designer has your number when you see her new line and think: wow. we have never seen anything so gorgeous before. Chantal Thomass's new Secret d'Alcove underwire bra has all of the trappings of classic pieces we love: perfect plunge balcony silhouette, light corseted boning in the band, leavers lace detailing, tiny bows, the glorious play of blush and black, of silk on lace… but somehow it all conspires to transcend, to an epiphany of that truly a-ha! stunning moment. That's something you can't plan and we think just might be the actual definition of sexy.
