Holy crap, Batman. I bought 2 new pair of jeans today, 2 different sizes as the smallest ones I have now are too big (just started wearing a few weeks ago). I just tried the bigger size on, it fit easy. The one smaller? Still fit. I lost 2 sizes and didn't even know it. I didn't try them on at the store because I just "knew" I had only dropped one size. My bad, got to take them back now.
Booyahhh
