Uniqlo wool collarless pea coat

Purchased from Uniqlo in Taiwan on a layover, hence the material tag, so I can't fully confirm the materials. It feels like wool to me, and is a bit thinner but warm. Hits me just above the knee (I am 5'7" for reference). No collar or tie. This is worn but has lots of life left. I was a size S-M when I wore this, would fit an XS-M depending on desired fit.
