Diaper bags are definitely improving! This Hansel Bag from Not Rational is super hip and cool! And it has all the essentials like a leather changing pad and some not so essentials like a bottle and pacifier, which I find kind of odd, but at least they are looking out for your needs. The exterior pockets are key to a good diaper bag and this one has 4! The center one with snaps is perfect for phone and keys, which always gets lost inside a bag with too much stuff. The distressed dark grey is not only stylish but will hide dirt and wear very well, it will take you to the end of the need for actual diaper bags (which is when your tot is weened off bottles). At Barneys New York for $695.
