I rarely review my purchases, but these are fantastic. I used the size chart on the listing and they fit perfectly. I am 54, about 165-170#, 32 waist and ordered a size XL/8. When I opened them I was afraid they would squeeze too tightly and be visible through clothes because they look like they have traditional elastic waist and thigh bands, but they are soft, stretchy, light, and perfect. I have never found a single garment that doesnt dig into my chubby thighs and leave a visible shapewear edge through clothes, but amazingly these do not! I ordered another Vasserette slip short with a vanishing edge at the same time, and these are far better for comfort and looks! I would order again. Totally worth it.  You should get them.
