Gonna throw out there I just got some Levis 541 Athletic fit denim.
They're tapered more than 550's, but the upper legs are looser for people with big butts and thighs.
For me, they're nice because they look baggier, but the leg opening is not as big so my pants never go over the tongue of my shoe minimizing the baggy raver effect.
I usually go 32's, but got 34's and think you should at least size up a bit to account for the tapered legs if you're going for baggy.
