The Petite Shopper holds a lot and depending on what you're wearing it with, it can easily go from casual to dressy.
I take it on casual outings with my son and I've taken it to dressy brunch with the girls.
When I'm out with my son it comfortably fits: wallet, cles and keys, 2 pull ups, travel wipes, hard case for sunnes, small digicam, cell phone, ziploc with snacks, small bottle of water.
Room to spare.
