I let my child wear this to cheer practice.. Do you allow your child to wear things like this to athletic practices?

She’s in competition cheer and this is what she wears to cheer practice.. All the girls wear similar outfits. She’s comfortable in it, it’s easier for her to move around and do what she needs in outfits like these and to me it’s showing less than the short short shorts show of their legs in practices so why is it okay to show off almost all of their legs but not part of their tummy? I have no problem with my child wearing this to cheer practice, she wears other like this as well and some came with the practice gear. I just thought I would see others views on it.
