Holly, a jumper dress with racerback bodice and pook-a-boo skirt by Modkid. Designed by Patty Young, Holly is an adorable jumpter dress that can be worn with or without an undershirt. It features a series of skinny shoulder straps that weave in a beautiful pattern onto a racerback bodice. Two very full gathered skirts provide maximum twirl power. A couple of drawstrings at the front give the overskirt a scalloped book, letting the underskirt peek out ever so slightly.
