There was an episode of Trini and Susannah What Not to Wear that had a big guy, and they did some sharp stuff with him. I'd love to find it, actually.
I think it depends a lot on the style you're going for, but one really great look is a tee and jeans/trousers of the same colour, with a shirt/sweater/jacket open over it in a brighter, contrasting colour or print.
If you do a google image search for 'large men fashion' you get some good stuff.
