Diaper Bag Desire

It's still a bit early, but I'm a girl that loves bags.  Having a baby certainly justifies a new, bigger bag.  Alan doesn't know this yet but I'm really not interested in a neutral diaper bag.  When faced with changing my first blow out in a public bathroom, I'd like to have an awesome bag holding the essentials.  Some of the fun bags I've found so far:

Kate Spade

Coach - also available in a gorgeous green

Carter's

Zara

 Maybe once I navigate what actually needs to go into a diaper bag other than just diapers and wipes, I'll have a better sense of what would or would not work.  Ultimately, it has to be functional but it can't be dull.  I'm certainly open to recommendations if you have one!
