This is a set of 3 baby leggings purchased from SOWAN, a very popular shop on Rakuten. They have great stretch, making them easy to put on, and my baby seemed comfortable wearing them. The size is unclear as there are no tags, but I'm listing them as size 80 because my baby wore them when they were size 80. The lengths are slightly different, but the stretch made it not a big issue (they were purchased at the same time). Worn for only one season. Would you like them for a low price, perhaps for daycare? I don't think there are any noticeable stains, but because the fabric is soft, there is some pilling and small fuzz balls. The inside is lightly brushed, but overall they are thinly made, so they didn't seem too hot. Therefore, I had my baby wear them from now until spring rather than in the middle of winter. I will remove a small name sticker that was attached to the stomach area. They will be shipped compactly.
