Would you like to try it? It's not the type that you pull on from the bottom; it's the type that you fasten with Velcro at the top and bottom and cross the belts, so it can be worn over a compress without rolling up. ⭕ I tried it on once, but it's new and unused. =Size= XXXL It is marked for thighs 10cm above the knee, 52-57cm. Thank you for looking.
