I liked the thick ribbed knit and bought it in three colors. I wash it at home with wool detergent. There might be a few pills, but I think it's a material that doesn't pill easily. However, since it's XS, I think the number of people who can buy it is limited, so I'm selling it as a set of 3. For those who purchase the set, I've priced it low, so please consider it. Thank you for looking.
