So after a lot of searching, I ended up ordering the Petunia Picklebottom diaper bag from Pottery Barn Kids. It was pricey at almost $200. 
Anyway, it arrived yesterday and I was really disappointed. It was pretty, but the openings in the bag were REALLY narrow... as in you could hardly open it wide enough to see into the deep bag. What the heck?! Total fail. And I didn't realize it, but PBK doesn't do free returns. (There's only 1 location in Manhattan and it's not close to where I live.) So annoyed right now. Back to the search... 
I ended up putting this one on the registry and hope it's better. It's certainly cheaper and has plenty of positive reviews. 
                 
                
Re: Not Happy with Diaper Bag
What friends o mine have done is just thrown their wallets in their diaper bags so they wouldn't have to carry a purse as well. And if you get a nice enough one just use it as a duffle bag after you no longer need to carry tons of stuff with you. I'm probably going to use my diaper bag and just a regular bag after. It doesn't look like a diaper bag
(One of my only baby purchases to date). It's cute and seems really functional - love the circular, detachable changing pad, too.
Mine is the "organizing utility tote". They also have a "super organizing tote" that is basically the same thing, but it zips closed.
