Snap bracelets, once Gen-X must-haves, are back, and this time they’re loaded. Ralph Lauren’s feather bracelets waft the Gen-Y fragrance Ralph, while participants in Tommy Hilfiger’s 13-city annual race for multiple sclerosis snapped up scented bands (available at Tommy and Tommy Girl fragrance counters nationwide in January). Michael Kors will use faux-suede cuffs to tout his debut scent, Michael, at his NYC fashion show Sept. 20. And a sequin-studded number promotes Givenchy Oblique’s hip new scents dubbed Play, Rewind, and Fast Forward. ”We thought it was an innovative way to sample fragrance, with a great fashion angle,” says a spokesperson for Parfums Givenchy Inc. and Michael Kors Fragrances. Being snappish has never been so forgivable — or smelled so sweet.
