It's funny how clothes sizes go: Small, Medium, Large, Extra Large, Extra Extra Large... Seems to me we should have an "Extra Medium" size (for the truly average). There's no rhyme or reason to the sizes either. Marks and Spencer Large really is very large indeed, whereas in France I tend to have to buy Extra Large, because their Large is really rather Medium. Here is my proposal for correct sizing:

Puny
Small
Medium
Medium-gone-to-seed
Large
Large-let-yourself-go-a-bit-have-you?
Obese
