Here's what I bought this year. I used them during the summer, so there's some slight pilling. The white ones have a slightly dirty neckline, but it's not very noticeable. They seem to stretch more easily than Uniqlo fabric, so please be aware that they may have stretched from washing compared to when they were new. I think they can still be used as underwear for the coming cold season. I've tried to remove any child's hair, etc., but I apologize if I've missed any stains or other imperfections.
