Sephora does it again! The beauty megastore has teamed with nail polish giant OPI to deliver a super-sexy summer collection, Havana Nights ($18). Inspired by vivid, bold island hues, these limited edition shades look equally dazzling on fingers and toes–and, we can attest, they last a full week without chipping. The collection includes: Read My Palm, an edgy green; Rumba Romance, a brilliant gold; Caliente Coral, an uber-bright peach; and Teal We Meet Again, a vibrant teal.
