Thanks! Yep, I normally don't like the crossbody a ton, but I keep seeing it recommended everywhere just for "security" during the crowded summer months, because of the pickpockets. We've never had a problem in Rome before, but we've always gone in Winter/Spring and keep reading that it's worse in summer.
I already have this little Prada nylon bag (but in ivory/light tan) that I wore last time. It fits snugly under my arm because it's tiny: Prada Small Nylon
But the little black messenger ones look ok to me, too: http://i.ebayimg.com/15/!BS9W6bg!2k~$(KGrHgoH-CEEjlLly3cCBKF42CY5Kw~~_1.JPG
I bought a cute little haiku one for like $30 a few weeks ago but have been having second thoughts about it: Haiku by Sharon Eisenhauer Grab Bag Hana by at Zappos.com
Think I need to look further, or am I set?
