I have a Prada nylon tote from 1993 that I still use sometimes. It came back into rotation after I had kids and it is so incredibly durable and easy to clean. You use a clean wet cloth and wipe the dirt right off! This tote with the outer pocket is the perfect "diaper bag", but of course it isn't really, which is why it is so fabulous. This army green is great for times when Dad needs to carry the bag (which is whenever we go out). At Saks Fifth Avenue for $550.
I am pregnant with my first child and have been on the hunt for a baby bag. Any suggestions on other designer bags that could double as a baby bag? I've been to YSL & LV, but nothing has grabbed me yet.
