My daughter is a just  starting to outgrow her size 8 clothes, she is slender. This swimsuit in 7/8 fits her well, but is slightly large in the bottom and the shoulder straps.  Skirt covers it, so its no big deal for now. I think by summer it will fit her well.  Skirt covers it, so its no big deal for now. I think by summer it will fit her well. Super cute though!
