The prettiest of them, says designer Nicole Miller, are "delicate and refined. Think capellini." Yet even when they're barely there, spaghetti straps—those wisps that keep slip dresses from slipping—can give a girl peace of mind. "It's a way of looking bare but feeling secure at the same time," says Miller, who dressed Angela Bassett in a satin spaghetti-strap gown for this year's Cannes Film Festival.

, "they accentuate the shoulders and show off the collarbone." And more, if you're so inclined. Sarah Jessica Parker
says she keeps her strappy numbers tight, "so I don't have to wear a bra." Which may mean that celebs like Demi Moore
, Ashley Judd and Toni Braxton aren't getting strung out just to play it safe. "Spaghetti straps are uninhibited," says L.A. stylist Jessica Paster. "They're hot."
