I would recommend wearing them over a thin camisole, though, because the material is somewhat stiff and rough (it has to be, in order to compress your body and support your back and abs.)

Note: these are not supposed to be for slimming -- in fact, they actually add bulk to your body, no matter how tight they are worn. If you are looking for something that serves the purpose of the slimming girdle, this is not the product for you. It is intended for healing and support purposes only.
