Not to pat ourselves on the back but we've really started to nail this whole women's button downs thing...this one features a crazy soft, heavier weight flannel that's a little thicker than our other flannels, so you can wear it like a shirt or an overshirt. 100% brushed cotton for ultimate softness and warmth. Charis (best hair in the office/city), is 5'10 and wears an Extra Small.
