I'm adding a third bathing suit to a previous listing. Most recent Speedo is a size 8, but on the smaller side of an 8 and in very good condition. Both other suits are also in great condition and worn throughout one summer season rotating among a couple other suits. They are pretty comparable in size, the Speedo Girls Thing Strap One Piece is a extra small and the Kanu Surf (purchased on Amazon) is a size 6. My daughter is thin and average height, she fit into them perfectly the summer she turned 6. Both have bright colors that haven't faded. The size 8 she wore when she was 7 and she was small to average in height and size.
