This beautiful item does not have a tag for sizing, material or brand. I placed a black slip under for styling idea but feel this would be amazing with so many styling options! Refer to photos for sizing there is not a ton of stretch. I believe it would fit a M or S best. It is too snug on my biceps (measures 6 inches width for upper arm). My loss is your gain! Some loose embroidery that can be easily trimmed.
