Navy and white striped (Baby GAP) - Size: 6-12 months Beige with white polka dots (H&M) - Size: 74 (approx. 6-9 months) The Baby GAP swimsuit has snap buttons at the crotch. The H&M one has soft, stretchy fabric, so it doesn't have snap buttons, but it was easy to put on and take off. I purchased both of these here. My daughter, who is of average build, wore them around the time she was turning 10 months old, and they fit her perfectly. (She was wearing swim diapers.) The swimsuit is stretchy, so she might be able to wear it a little longer, but I don't have any plans to go to the pool, and I figured she probably wouldn't be able to wear them next year, so I'm putting them up for sale. I will compress them and ship them together.
