Thank you very much for looking! The fluffy pants and pink pants are clean, having only been tried on over underwear, but I've cut off the size tags, so I don't know the exact sizes. They stretch very well! I think they would be fine for elementary school-aged children. How about wearing them under a skirt? The polar bear socks were only worn inside the house for one day. They're not from Gelato Pique, but I recommend them to those who like fluffy items (*^^*) Sorry, no price reduction m(_ _)m If anyone is interested in the 3-piece set, please consider it (*^^*)
