Petunia Pickle bottom diaper bag???

Koru00

I know there are a ton of posts dealing with diaper bags, but I can not stand the traditional bag.  I like bags that look a little more like a purse. I also really hate diapers where you have to stack stuff ontop of other things & than you end up digging.  I really like the design and style of the Petunia Pickle Bottom wistful weekender bag. I'm curious if anyone has bought this style bag and could give feedback on the size & if they thought it was a good size.
