Nubby silk noil. Only worn a few times, hand washed recently. I don’t see any glaring stains or discoloration but included pics of underarms since it is white. Small pinhole near the tag doesn’t impact function/ wear. Would trade for a medium in any color, I love this but I feel like the arms in particular are just a bit snug and it is so delicate I don’t wanna be aggressive getting myself in hahaha. Let me know if you have questions
