Perfect fit and great value
Size: X-Small, Color: Black
This suit was absolutely amazing and fit my son perfectly. I was a little apprehensive about buying a suit from Amazon, but it exceeded my expectations. The quality is great for the price and it looked really nice on him.
It was definitely worth the money, and I would absolutely purchase again.
