Purchased at a BeneBene store in Korea. It's been used for everyday wear, so there's a feeling of use, but no noticeable stains. These leggings are very soft and suitable for autumn to winter. The waist is elastic. It's size 12m, but I dressed my child in them around 6 months old. I have washed them with fabric softener, so if you are sensitive to smells, please take measures to remove the odor.
