I'm on a DwellStudio kick these days. Just love the modern prints and lines of their designs. This is one of the best totes I've come across yet... and I do look! Functional, fashionable - not too big, not too small. Need I say more? Simple.
One other bag I absolutely love - is definitely NOT a diaper tote, but I have been known for using everything but diaper bags to tote the diapers and wipes. So, I must mention a non-diaper tote, tote. With so many options, this bag would work for so many personalities. Timbuk2 offers a "build your own" feature. Love it!
