i wasn't sure if i wanted to buy this after reading some of the reviews about it riding,but i went ahead and odered to try my luck because i had a x-mas party to go to and i have this pooch from having a baby on my tummy still, i am 54 147 lbs right now and i got size med. it did ride a little if you sit for awhile and do alotta bending,i found it works pretty good tucked in with jeans tho,it hold it better . its nice and duddle layed so it does smooth out the unwanted spots okay . i wish more lol im not sure how great it is compaired to cheaper ones at walmart ive never tryed any other of these before but ide say its a 4 ,lets face it theres no way your going to get a perfect mid section without working out,but it did help me feel a bit better in my clothing .it probley would ride less if you get a size that fits right,but then again it won't push in as much eaither,but fat is fat push it in it just goes someplace else.;)
