Reformation Sierra Stripe Button Front Tunic Dress

Reposhing this item I purchased from @houseofreloved. Loved it so much, but it's too short for me (I'm 6' and didn't pay enough attention to the measurements!) The label says M but it is definitely not - it's a size S. Made from surplus fabric (unknown) but feels like cotton. Mandarin Collar Button-front Long sleeve Small hole in back has been sewn (previous Posher) and is shown in pictures. Belt is missing. Measurements (flat) are in photos.
