I saw this exact same costume in the stores for $10-$15 more, so I was happy with this purchase.  My daughter looked very cute in it.  She wears a women's size 1 or 3 pants and a small or medium women's shirt (she's 5'3"/95lbs), and this costume fit her just fine. She did wear a black t-shirt underneath because the spaghetti straps aren't allowed at her school.  It was still cute as can "bee."
