Heres another design I just did.
Now I'll explain my thinking behind the sports bra thing... so I was thinking the teal sports bra would be an actual sports bra just worn under the uniform but meant to look like part of the uniform. This gives the possibility of having more cutouts but still letting girls wear normal sports bras. And this could also give the team ways to easily change the look of their uniform without having to buy a different top or skirt. For example for a day 1 look the team could have the teal sports bra and for day 2 the team could have like a black or maybe gold sports bra. Also more gifted girls could easily layer another more supportive sports bra underneath if needed.
