I usually wear S or M, but Gap tends to run large, so the XS was a perfect fit. I haven't worn it much, so I think the condition is good. I'm selling it because I don't wear it anymore (*^_^*) Instant purchase is OK. 100% cotton Gap long-sleeved shirt, XS size, with a chest pocket. - Brand: Gap - Model Name: 1969 - Size: XS - Material: 100% Cotton - Design: Long-sleeved shirt - Pocket: Chest pocket Thank you for looking.
