Great style; unique; fits well.
Size: Medium, Color: Gray
Love the style and the fit. I get a lot of complements wearing this. With only three buttons, wearing this outdoors in the cold might not be practical. Other than that, I like it. I went back and ordered a second coat but in a different color.
