How do you pull your look together?

I've noticed that I really love looks where the belt and the shoes are the same colour...to me it is "polished."-- which is one of my goals.

But I would NOT be happy wearing a belt. Basically, from bust to belly I am all one size--this apple is more than happy to surrender her waist!
But it does make me wonder what options I have....

Thoughts? If you have links to images of larger fashionistas, I'd love to see them, too. Thanks!
