Thank you for viewing! ^ ^ This is a set of 4 short-sleeved undershirts from apres les cours. The size is 90. These were purchased for nursery school and were kept as spares. They are made of a waffle material? and weren't very thick, so I didn't have my child wear them on cold days. I switched to tank top undershirts when it got warmer, so they were worn very few times! There are no noticeable stains, but they are used items, so please understand this before purchasing. ^ ^ I also have long-sleeved sweatshirts, outerwear, etc. for sale, so please take a look ☆ Discounts are available for combined purchases ☆ Thank you! ^ ^ *Please be sure to read the notes in the profile section before purchasing ⭐︎
