I have a 40 inch waist, a size 14 16...and I use this item on a daily bases to smooth out those stuborn areas... It is comfortable and works... I do not feel hot, you do not see lines, and it really pushes the boobs up..but not to much. I wear my bra over the top of this item for better comfort, but you can try and see what you like beter. I do wish it was like a body suit to help it from sliding upwards...with a snap for easy bathroom use, but its just a top...but I still love it... I wear it with everything, pants, dresses, and short/skirts... LOVE IT!!! This product does not role, if it does you need a bigger size. I do have to pull it down and rearange after going to the bathroom, or sitting for a long time period. but not to much... not a deal breaker.
