Latest research shows that UK males are catching up with their US counterparts in the Easy-Fit department. The average UK male has a waist size 12" larger than mine. Its hard enough finding decent trousers with a 30" waist, it can only get more difficult. Ive given up finding shirts that fit me. If the arms are long enough, its shaped for a large gorilla.
Before all you guys and girls shed your inches, just consider the downside of being slim.
