Designed to be the "cherry on top" of the Katy Onesie, this active jumper pulls together the entire look. Featuring bell-sleeves and a hidden clasp at the center, it has fun and flirty written all over it. Wear this as a set with The Katy Onesie, or throw it over your sports bra and leggings for a cardigan-inspired piece that you won't feel guilty sweating in.
