This is a long-sleeved blouse from Blue Label Crestbridge. It's size 36, which is equivalent to a small. It's quite sheer, and the sleeves have elastic. The sleeves have a slightly yellowish pattern. The collar is a detachable collar that you just place on (?), and tie with a ribbon. (I haven't used the detachable collar, so I'm not sure if the ribbon goes in the front or the back) I bought it in the winter of 2022 and wore it a few times. I didn't wear it much because I don't really like the elastic cuffs and the frills. There are stains as indicated by the red circles in the photos.
