Oh my gosh!! These are exactly what I have been looking for!! They are snug enough to stay on, short enough to be able to wear them under shorts, loose enough to forget you have them on, and the material is such that other clothing will glide over them. However size up! I wear an XL in stretchy pants like yoga or pajama pants. I wear about a 18-22 in blue jeans or khakis depending on the style. I purchased the 4XL in these. I didn't want shaping shorts, and I didn't want them cutting into my waist. The material is like panty hose material: stretchy and potentially sheer. However they are big enough that the black ones appear solid not sheer on me. The most important thing for me is to be able to wear them, forget i have them on, and-the biggest reason- prevent any chafing. I will definitely get more!
