Pastels are so sweet this summer—not only are the delicate tones a smash for hats, hair colors, and nail polish, celebrities also love the soft shades from head to toe. Catherine, Duchess of Cambridge chose tender yellow Emilia Wickstead, Emma Stone went for sky blue Emilio Pucci, Salma Hayek sparkled in an embellished Bottega Veneta violet sheath, and Diane Kruger looked ladylike in icy blue Chanel. This is a look that is as sophisticated as it is romantic, especially when paired with neutral tones for accessories and makeup.
