What bag do you use for the gym? I'd been using a big Longchamp Le Pliage but find that I need more space (and more organization) now that the kids are coming with me to go to the kids club/daycare, and we often go straight to the pool afterwards...so I'm lugging a ton of crap and it needs to be easy to find with three squirming littles!

Cute is a must, and bonus points for monogramming option.
