Poppy King x Kate Spade:
After the two brands collaborated on lipsticks last season, nail polish makes sense as the obvious next step. The line is inspired by Australian artist Florence Broadhurst, and comes in a set of four mini polishes: Watermelon Fingers, Sea Foam Swirls, Solar Orange, and Yellow Cockatoo. Snag the set for $28 starting in April at katespade.com.
