Scuba Diver Baby Costume

This is my son Corban. He is 8 months old. The inspiration for this costume idea came from a variety of posts on Instagram. The tank on his back is a 2 liter that has been spray painter silver. I cut two slits in the bottle and ran a long piece of fabric through them. This acts as the strap to play it on his back. I then put a straw coming out of the top of the "tank" and ran it to his mouth where I taped it to one of his pacifiers! The rest of the outfit was just black clothing and some swimming gear from around the house. Cost: Free. We had everything in our house already!
