Can someone suggest a men's bag for me?

Jun 18, 2008
I wear a lot of sports coats and blazers and I find that the messenger bags I usually carry tend to mess up my coats. Can anyone recommend for me a good everyday "hand held" men's bag (preferably not a brief case or a huge duffle) and under $500. I usually wear a lot of black, brown, and silver/gray blazers. What color bag would go best with those colors?
