what??? Brown...especially that chocolate brown color is so popular right now. I personally think it's an awesome color. I too have one of those choco workmans UK's and I find that since it's one of those warm "uncolors", it goes well with everything.
I can wear it with black accessories, and black sweater. I can wear it with my brown leathers. It looks great with printed shirts.
I love brown. Did I mention I loved brown??
