I thought I could wear my fat clothes without any problem. I was hoping to wear them out first, but someone took a picture of me and Charlie at a restaurant on fathers day and the shirt was so big I looked like Jabba the Hut so I have been buying a few new clothes. My pants waist size is a loose 36 now. It was a little snug at 40. I think my shirt neck size has gone down a couple of inches.
