Princess Cut Set

I receive a Bridal Set QVC Diamonique. Can you help me with this question?
My husband is buying a princess cut wedding set as my QVC application. (I've never one six years later .. .. long story;) Any hoo, how many carats would be "realistic"? I do not want reach is so great that everyone looks and laughs at me. What do you think?

If you are small and fingers are small, thin, I'd say do not go more than a carat. If you are larger boned, you could go to 1.5 and still appear realistic.
