This contemporary or commercial dance costume has wide leg pants and a mock turtleneck crop top with lace and rhinestones and an open back. We bought this last year, my daughter wore it once, misplaced it, I bought another costume, then she found it. Yay. Bottoms are Balera and top is Ivy Sky by Weissmans. For sizing, please visit Balera's site and Wessmans. My daughter was 9 and I can't recall her measurements or weight, but an average weight kid, average to slightly taller in height.
