From about 10 onward, not only did I wear jeans, but they were purposely tight in the waist... basically, they were a combination pants/girdle, lol. Over time, the compression carved my midsection into a more appropriate shape than the one nature saw fit to give. If I hadn't done that, I'd have had no waist at all and would have indeed gone through life looking perpetually pregnant. Looking like that isn't even an option, in my book.
Now, I'm not entirely certain I want to see what fun and games that wreaked on some of my internal organs. (I'd imagine that a surgeon would practically need an ice cream scoop to extract my gallbladder, for example.) However, if I had it to do over, I would again do the same thing.
