Don't waste your money. It is a far stretch to say I noticed a difference AND you could see the outline of the butt pad. Also, the outline of the panty line showed and my butt cheeks were falling out of the bottom. I don't have a "pancake" butt, but I also do not have a "big" butt. I'm somewhere in between... but every girl wants their butt to be a little fuller- right? I wear a small in regular clothing and these did not fit appropriately. It was not a smooth fit like I was expecting. Everyone's body is different, so maybe these just didn't work for my particular shape. Also, the butt pads sit more at the top of your butt than on the lower end. It was just a weird scenario all around. Not sure how the reviews were so great (the whole reason I ordered was because of the good reviews). Oh well- bummer.
