Black turtleneck with knit ribbed neck and soft flowy body

I got this unique top at Alter in Brooklyn, it’s made in Portugal from a combination of ribbed knit material at the neck with a thin, soft flowy body. Labeled size M but could work on S-L depending on desired fit. It’s longish, almost like a tunic on me (5ft4”). I wore it to work once, otherwise basically new. Pit to pit: 20” Length from base of knit to bottom hem: 25”
