i have a long torso, so this isn't that comfortable to wear.  it's actually too uncomfortable for me to wear during the day.  the top only reaches to my bottom rib, so the top band doesn't have a flat rib cage to lie against.  i had to keep hiking it up really tight, or it would roll down.  i am now only wearing it at night (when i don't move much), and even then i have to keep pulling it up really tight or it digs right under my rib cage and hurts too much to sleep.

also, the stiff band on the non-zipper side REALLY digs into my side, and i have to constantly pull that up too so it won't hurt too much.  another reason i only wear it at night.

that said, i think it does compress well in my tummy area.  i think if you have an average size torso it would be great.

i have the Small.  i'm 5'4", 130 lbs, 38.5" hip.
