Stay Puft Marshmallow Man Costume

My son, Ben, recently watched Ghostbusters (1984) with his dad. He has since loved the movie. When asked what he wanted to be for Halloween this year, he yelled "The Marshmallow Man!" The shirt and pants were made by layering two shirts (two leggings) inside of each other. I bought clothing that was three sizes bigger than Ben's normal size. I then stuffed between the layers with poly-fil. I had stiched to add the "fat roll" look. The chef hat was purchased from Etsy. I then added vinyl letters that a friend made. The tie and bib are made of felt (ribbon trim on the bib). The ribbon on the hat is also made of felt and secured with a blue button. Ben wears suspenders to keep the pants up.
