This feels so natural because it is not to thick or bulky, it gives you just the right amount of padding. The pads are sewn in so they don't shift or move. The trick is to order the correct size and that's just a toss up you either hit it or miss it. I ordered a large and I did alter it by hand stitching the crotch area tighter so that the padded butt part would lay perfectly on my cheeks instead of rising above my cheeks. The pads should not be high on you butt. I will order a medium because the product is good. I also suggest wearing panty liners or another pair of panties on before putting on the butt pads to preserve them because washing them will more than likely mess up the unit, also try hand washing very gently. Also you can't see any lines under clothes other than regular panty looking lines. not noticeable at all!
