Two One Piece Swimsuits Gap & Cat & Jack

Two girls, one piece swimsuit the multicolor floral is from gap. The only sign where is pilling at the tush see photos please. Size medium. The second is a multicolor one piece from cat and jack size large 10-12. This one also has paddling at the tush, and a few little marks at the front of the tummy see photos please. My daughter wore them at the same time so I don’t think the cat and jack is much bigger.
