Shark Attack Costume

My boyfriend was hurt while working on an oyster boat 14 years ago. He caught his hand in a wench. I bought my son a shark costume (last minute so options was limited). On my way home I came up with the idea of a shark attack. My son is 10 months old. My boyfriends costume is an old shirt with one side cut up. I spray painted red on the shirt for some blood. I wrote I survived a shark attack in black paint marker. Then added tattoo cuts and fake blood.
