Break out of your NYC LBD rut at this boutique, which counts Katy Perry among its celeb fans: You’ll find tons of brightly hued, bohemian outfits from designers like Peter Som, Sonia Rykiel and Basta Surf, perfect for showing some beachside glamour. And don’t sweat it if you didn’t buy something you loved when you were there: There’s an Upper East Side location too.
