This is a set of 7 shirts for suits. As you can see in the photo, the 4 shirts on the left are 100% cotton, and the 3 shirts on the right are cotton and polyester. The bottom two shirts on the right and the second shirt from the bottom on the left have slight stains around the collar, but they are not noticeable in the photos. Otherwise, there are no other stains or issues. The top shirt on the left has only been worn once and is almost new. Thank you.
