I just got this package,and I already ordered the second one in Nude color.this is amazing,specially with dresses. I listened to the reviews and ordered a size bigger than my actual size which I regret. If you have small thighs you go with your own size because the pressure is the highest around thighs. I ordered the nude one in size M when i receive it i'll upload photos of both colors and sizes. i'de say if it is not that tight it won't lift your buttocks up,so if it is not killing you go with your own size,since it is really flexible and quality is good.but if you have chubby legs then well..Also if your size is on the border of for example L and M then go with bigger one. I'm the type that my upper part  is larger than legs and bottom ,
