I think this will be useful in the fall and winter. It has a distinctive shape, though I don't know if you'd call it bat-shaped. I've been told several times while wearing it, "You're wearing a stylish outer." It's a loose-fitting black silhouette. - Color: Black - Design: Buttoned, loose silhouette - Material: Unknown, but feels lightweight - Pockets: Two front pockets Thank you for looking.
