Denim by Katie Holmes

For some reason, Katie Holmes seems to be a harbinger of jean trends. Remember how we saw her a few years ago wearing baggy, hole-y, pegged jeans in paparazzi photos and we all laughed. Then those same jeans started showing up in stores as "boyfriend jeans."

Well watch out, because based on this picture, I am predicting that bellbottoms are coming back in. Don't say you haven't been warned.
