I was looking through my drawers a few months back and came accross a load of my old band Tees from the late 80's early 90's and they are all XL!! Now considering im 5'5" and up until i hit my 30's I was a size small!!! WTF was i thinking, I put one on and my missus pi55ed herself it was like i was wearing a tent!!! Middle aged spread has got me now and Im a Medium now!!
