Thank you for viewing. It's a free size, but the size feels like it could fit up to XL? The draped design gives it a relaxed, loose fit. I received it from a friend who bought it, and I haven't even tried it on. There's a faint black mark on the lace in the back; it seems to disappear slightly when viewed from different angles, so it might not be a stain, but I'm not sure. Please check the last photo. Both the lace and the blouse are 100% cotton. The lace is removable. Feel free to ask any questions.
