I usually just throw a cloth camera wrap around whatever I choose to shoot that day, and toss that into a messenger bag that I put some adheasive foam padding into on the bottom. Sometimes I will just carry the wrapped camera on my shoulder, and fold away the wrap into my back pocket, or tuck it into my jacket when I get to an area I want to shoot in. The wrap makes it looks a bit like a murse haha. I have been leaning toward waxed canvas for a the last 3-4 years now, in the past it was ripstop and waterproof nylon but the canvas is really nice when broken in and doesnt scream camera bag. One other thing, those gaudy big camera straps with the company logos across it should be left off the camera, nothing screams look at my and my camera than those straps from a block away.
