In the end, business isn't about wearing nice suits or looking the part. It's really just about being true to yourself, your ideas and focusing on the essentials. Handle your business first and everything else will follow suit.
Go ahead and break up a suit. Take some risks with your jacket or pants. Just remember to maintain a sense of balance between your top and bottom halves. If you go bold on top with a pattern (like this plaid) or a color (white, midnight blue) or a texture (velvet) balance it out with something basic down below.
