I'm fairly long-waisted and I don't have this problem. I agree, it would be helpful to see reviews describing their body shape so we could know how it would fit us.Same here. Could be more of an issue, I suppose, if you are really long bodied: so the bit that should cover your butt is where your waist is.
If people described their physique, when reviewing, all would be explained about who it would be better for.
