Grey Ribbed Cardigan

Purchased in Seoul, Korea and in great condition- no pilling, rips or tears. No label but it should fit xs/s. It buttons up and comes with a matching belt. For reference, I'm typically small and would say that this fits true to size. I am 5'7 and it hits me at my knees. There's no label, but hand wash or machine wash cold just in case and reshape whilst damp.
