This is a set of 4 short-sleeved and sleeveless undershirts. The short-sleeved ones are made of gauze fabric and show some signs of wear. The sleeveless ones are thin and have less wear. All are 100% cotton. There is a small stain (lower left front) which is difficult to see in the third photo. I am also selling other children's clothes! If you purchase multiple items, I may be able to offer a discount, so please comment if you are interested.
