Shirt sleeve rash guard, white, 12 months, 18-22lbs Swim diaper, under the sea print, ruffle butt, 5 button snap closure, 18 months, 22-25lbs My daughter wore this once or twice last summer when she was 12 months, the swim diapers need to go up a size due to wearing a normal diaper underneath but with these you don’t have to, I just always had her in a swim diaper underneath.
