I sized way down
This is basically a poncho with arm holes. but it looks great and is well-made. 
i got this in the wine, which is a beautiful color. the design is nice and looks expensive (but i'm not sure how it will hold up after washing), it is oversized and a little boxy. i'm a medium or large on top and i ended up purchasing an xs and it fits just fine in the shoulders and arms. the rest of it is still roomy (though short) but perfectly fine. i got this on sale, so it was well worth the price point.
