I was at a loss knowing what to call this unique, gorgeous piece. It's sort of a kimono, sort of a coverup, sort of a cardigan, sort of a shawl, yet not really any of those, exactly. 

In terms of construction, it's made sort of like a shawl with holes for your arms; how much of your arm sticks through will depend on how it lays on your body. 

Although the size on the label is 2X, my mannequin is XS and it looks pretty good on her, and widthwise it's 37" (74" across), so I think it could reasonably be considered one size fits most.
