With sneakers and a shoulder bag, it’s a cute daytime outfit. With grip socks and a tight ponytail, it’s a perfect Pilates look. With its boat neck, bell sleeves, bootcut legs and figure-defining waist seams, you won’t want to take this onesie off. It’s finished with a chic open back and made from buttery, brushed, cozy-as-can-be Alosoft.
