This is VERY small! My daughter wears 3T/4T, we ordered size Intermediate 6-8 and it barely fits! (For reference she is 4 and a half, weighs 38lbs, average size for her age) When wearing it over her leotard, it's too tight for her to dance comfortably. It is very thick and the quality looks great, busy be sure to size up 2 sizes!! We will be returning this
