My daughter is very slim, but tall for her age. She is 13 years old and has been wearing crop tops for a couple of years now, but needs more support now. But, she has a very small ribs measurement, at just 22 inches. Over ches is 27 inches. I have no idea where I can find this size. I've looked at sorts bras, which is her preference, but none go small enough. Does anyone have any idea where I can find simple sports style pull on bras, nomfastenings, that would fit. She is also 5 ft 5 so too tall for children's sizing, the ones she's wearing now are uncomfortable.
