E-pic props

My photographer told me to bring some props like a flower or scarf to the shoot. Those items aren't really my style so I would like to pick your brains about what you brought with you.

I want him to bring his giants jersey and I'll wear my stepsons jersey for some pics, but what else?

If my photog said that, I'd bring my doggie! Might bring her anyway!

Other than that... hmm maybe some caps (like if you're sports fans)?
