I bought this item back in 2016 and loved them so much I have worn them out. Bought this pack but ordered my size L-XL based on all the sizing info. I am 5'7" and weigh an unfit 150. Way too small. I returned them and bought the 12 pack in size 2XL. They fit beautifully. Very happy. I do not wear a 2XL in anything from anywhere ever. Don't care they fit. Don't be afraid to order a size or 3 larger. If they fit you, you will love them. They are great under or over work out cloths and/or leggings because there are no panty lines. Awesome.
