Just in time for summer, Kate Spade is teaming up with Australian lipstick brand Poppy King—but this time, the collaboration is not lipstick. Instead, the two brands have created a colorful nail polish collection inspired by the bold works of Australian artist Florence Broadhurst. The line includes four colors—Watermelon Fingers, a bright watermelon pink; Sea Foam Swirls, a vibrant sea green; Solar Orange, a fiery orange; and Yellow Cockatoo, a sunny yellow—which are all perfect for summer. The entire collection will be available at KateSpade.com in April. Rather than buy each color separately, the entire collection will be available in a pack-and-go set for $28.
