Thick, stretchy ribbed knit. Can be worn alone as the shape of underwear doesn't show through. Worn a few times, but in good condition. I'm selling it because turtleneck sweaters don't suit me. - This knit has a substantial thickness. - This knit can be machine washed, making it easy to care for at home. The image looks a bit odd, but it stretches out like the first photo when worn. Please refrain from purchasing if you are overly concerned about storage at home. m(_ _)m
