I think Xtaby's idea is a good one, because what belt works has a lot to do with the rest of the look.
Here are my favorites, but just because I like them, I don't necessarily think you should get same. It depends on your style.
I wore this fancy sash/belt with a simple dress to a wedding rehearsal dinner a couple years ago. It's from Soft Surroundings, was marked way down and worked just right. Still love it, still have it, still don't know when I'm going to wear it again.Wearing it around town for no reason would have people calling you Delta Dawn.
The flower belt is a favorite too. It's a Target cheapo to replace a leather one from Ethiopia I've lost track of. I like to wear it with jeans and these boots in an outfit that can't decide if it's cowboy or boho. But if you hate those styles, then this is ew for you.
I like this belt bag a lot, but it doesn't live in my closet. Maybe I'll get its cousin this fall. But if you like to carry a bag, then having one on your belt is superfluous.
So show us what you've got, and what you like, and people will comment.
