Purchased this for my 7 year old who normally wears size 7/8 in clothing. We tried on the 10/12 and it was still a bit small. The gloves are teeny tiny and I had to sew the bows on the gloves back on because of poor quality. The leotard itself runs large around the collar and very very small around the waist. It is NOT a leotard so shorts are needed underneath. The tights are super small. The size they give you seem to be toddler size...almost ridiculously too small. I had to resew the wings because the strap came off while my daughter was trying it on. Glad I didn't pay over $20 for this poorly made item.
