O's Exclusive Preview of Narciso Rodriguez's eBay Collection

THE "IT" DRESS

"Narciso's clothes have drama, but they're never loud or overdone," says publicist Blanca Lassalle, whose clients have included Marc Anthony and Jennifer Lopez. Take this matte jersey sheath ($250), which tweaks the usual little-black-dress concept with a surprising off-center slice of color. Lassalle likes the combination of dark-and-slimming and a "festive" touch of red, and she considers Rodriguez's tailoring unmatched ("It hugs my body in the right places"). Another asset: It can go straight from work to evening.
