There is a lot of Birkin in the Spring collection’s Chantilly lace and hand-crochet cotton cashmere caftans and minidresses, low-slung pants and crop tops, some worn with boyfriend jackets, and almost all paired with flat sandals. Kors has always had a knack for neutrals, and this season focused on matching them to all skin tones on cashmere, breezy silk chiffon sundresses and easy suiting.
