From the pattern:
Wear it as a dress, wear it as a coat. This conventionally versatile classic is made with a soft, warm, and amazingly lightweight wool boucle yarn. A wide box pleat at the back provides additional fabric for the hem to swing attractively without adding unnecessary width to the upper body.
