Hello, I ordered a couple pair Smartwool undies (sport underwear). When they came and I saw them I could tell they were too small, I have a pair of Smartwool undies that I love but they are a different style (PhD seamless). I compared them to the ones I ordered and there was a big size difference, I did not try them on. I kept all the packaging and got a different size. When the new size came I washed both pairs and wore one, within a few hours they had stretched out so much that the leg holes were baggy. I'm bummed because I love my Smartwool PhD seamless. Will I be able to return these? Thanks!
