Ref- 5’4”, 150lbs (always a medium in leggings)The leggings are great, I own 4 pairs. Good fabric, not transparent at all. Very comfy, not restrictive ! These leggings are very flattering. Most importantly for me is how they feel on the skin, I have eczema so sometimes having fabric that sit close to skin can be uncomfortable, these are just fine. My only complaint is after a few hours they start to fall in the crotch with is kind of annoying but after washing they’re back to normal. It’s not too bad so it’s not a deal breaker for me. I’d order more if they became available in my size/ colors I don’t already own.. great purchase
