I'm thinking of commissioning a polo coat (double breasted, peak lapels, 6 buttons, full wrap around belt). Originally, I was thinking of staying with the traditional camel hair, but am wondering if that might be much. I work in a conservative finance environment and was wondering if I might be better off going with a navy color. Is that ever done in a polo style with belt? I already have a black cashmere chesterfield coat, so wouldn't be my only one. Thoughts?
