Belt Labeling

Problem1: Sometimes when you gain a little weight, your belt size increases by one or two holes and you don't even realize it.

Problem2: Some people buy the wrong size pants, not realizing their true size because they cinch things up with a belt adjustment.

Solution: A belt that has labels above each of the holes indicating the corresponding waist size. So it will be immediately obvious, for example, if you slip from a 32 to a 33 by going out one hole in your belt. Is there any reason not to have these labels? It would be so easy to do. I think this is a concept like those tagless t-shirts they came out with a few years ago. Once someone starts doing it, it will become an expectation for all belts (except reversible ones).
