For this you would also want to avoid sheer pantyhose, which is any pantyhose where it is more see through, because those are a lot more thin material, and so the ones that are less see through (Also called Opaque Pantyhose) would be thicker, and help give you a more smooth shape. There is also body shaping hose that would work just as well too!
Also pantyhose just feels lovely, you'll feel very girly the whole time!
