Justice Girls 2 Piece Long Sleeve Rashguard Swimsuit, Sizes XS-XL

It's tricky to find a modest, well fitting, appropriate swimsuit for tweens. Before this we tried the wonder nation brand, which had no bra included and material was FAR too thin, you could see through it in the chest area. This one is much better. I still wish they were a thicker/ better quality material, but this does the job. It does have a shelf bra included - with sizes Medium and up. Take note if youre also looking for something modest, the top doesn't actually cover the tummy completely. It's more of a cropped style and comes to about just above/ just below the belly button. The waist of the bottoms were a bit loose on a slender body type but she wore shorts over them anyway. Overall we were happy with the purchase and she swam with no complaints.
