I never bought a diaper bag. I figured I would discover what I needed and then buy one.
Well, LO is 3.5 months and I still haven't bought a diaper bag.
I used a mini utility tote from 31 and didn't keep using it because nothing zipped shut. (8"length x 6.5"tall x 4"deep)
I used a great bag from bungalow 360 (the pocket bag) but it is heavy because of all the pockets--and the front pockets don't close so I have bent over and dumped out my cell phone into a creek. (12" x 9" x 4")
I used a very simple box-like purse with no compartments and everything fits perfectly but it is hard to get one thing out without lifting everything else out. (10" x 7" x 4")

See, I have always been a tiny-purse lady and this diaper bag throws me for a loop. I really need something cross body...

Recommendations for a purse I can convert into a diaper bag. Nothing bigger than 12" x 9" x 4"?
