Yeah, I came across a pair of size 11 (juniors sizing) Roxy board shorts from my high school days. I am the same size now that I was then, and they're snug; supposedly I'm a size 8 now. Of course, Roxy sizes have always run small. But they've been doing this for years--this is why it's always a good idea to try clothing on.
And when people say they go by how their jeans fit to gauge their weight gain/loss, that's not always the best measure, unless you're using the same pair of jeans year in and year out, or they're hanging on to a pair of Levis with clear measurements on them!
