Lovekider Girls Swimsuits Two Piece Rash Guard Set Short Sleeve Bathing Suit Liner Swimwear with Sun Protection 3-12T

Ooh! I feel very qualified to answer this, as we have a kiddo with similar needs. Try a girls two piece suit that has a skirted bottom — a skirt over shorts. This swimsuit is a year or two old and out of stock, but the Amazon “shop” sells others with the same cut but different patterned fabric.https://a.co/d/0bcza2gn Another option is a “girl short” two piece. We have used this, and found it had enough room:https://a.co/d/03JyvDpP I sent those links to offer a couple style examples. There are obviously many similar products available. We need sun protection, so our tops have sleeves, but you can easily find similar bottoms with different tops if you desire. If you ever need undies, “girl short” styles work best for our kiddo. Boxettes brand has been very comfortable, but there are lots of options.
