I ordered these based off of my measurements and the size chart provided. I normally wear a medium in all leggings, but as my waist/hips measures 27"/37", I ordered a size large. The large fit just fine, pretty much exactly like my other leggings from other brands.The fabric on these are thin and very soft and comfortable. They do NOT have compression. They aren't tight. They honestly feel like a second skin I can imagine that due to the thinness of the material, the light colors may be see through with dark undergarments.I haven't noticed them accentuating any lines or wrinkles more than expected. They seem to be quite flattering.However, due to the fact that I am 5'2", these aren't cropped at all on me ? on the flip side the pockets are HUGE and will fit so many snacks, as demonstrated by the big water bottle I put in mine.
