These are maternity spats, with Uniqlo on the left and Muji on the right. The Uniqlo ones are thin, while the Muji ones have lines and are a bit thicker in the leg area. I bought both of them last year and wore them a few times under pants from autumn to winter. I mainly wore dresses, so I didn't wear them that often, but you can see some slight pilling if you look closely. Please understand that these are items stored at home and may have some fold wrinkles. I will fold them as small as possible for packaging. There may be a change from Yu-Yu Mercari delivery to Raku-Raku Mercari delivery. Thank you for looking.
