I got this for my 11 year old who dances. She wears a child’s size 12, so I got an XS and it was perfect. We tried several other dance bras and she didn’t like when you could see them and she felt like the strapless was falling.
My daughter cheers on 2 teams, and both uniforms have keyhole backs or cutouts that show straps. This bra is discreet and stays in place. Perfect!!
