I have purchased many diaper bags in the 11 years I have been a mom.
Never have found one that I loved.
Currently using this purse that I bought at Costco (its from The Sak) and its been the best so far.
Inside-
a couple of cloth diapers,
pink Kawaii and
white Fuzzibunz onesize to match her outfit today (I prefer they do),
a
Planetwise wet/dry bag to put soiled diapers in,
a
Trio bar,
My wallet (the yellow thing),
a small container of Puffs for Natalie,
Wipes, both disposable and cloth,
a small notebook to write things in,
a pen or 2,
diaper cream (not to be used with cloth diapers, though),
and probably thirty other things.
And don't forget, my camera is usually in there, too!
