I'd say so. I just loaded up on a bunch at the outlet in Vegas and normally wear size 6-8 depending on the brand, and most of the size small fits me fine. They carry some different jean brands though, and sometimes I'm a medium in those, but that's normal for jeans to fit weird like they do when we're not pregnant! Don't even escape that when looking for mat clothes!
