Learn To Swim Life Suit Toddler 1-4 years

This has no size tags but I bought it for my son when he was just a year old. He used it last year when he was four maybe twice and every year before that about two or three times at our family reunion. Has some staining on the back and a little on the front. It’s been in storage. Other then that it’s in excellent condition. I havnt tried to remove the stain I’m not sure if it’s from the sun or storage. Or if it will come out but there is no damage to the suit other then some faded staining.
