It's a great everyday bag, though I have to be honest and say that it doesn't fit my normal wallet (MBMJ Softy Zip Clutch). But hey, that's what skinnies & wristlets are for right?
I realized my pictures of the inside of my purse don't really give you any depth perception so you can't tell just how much room is left. For reference, yesterday I put my cell phone, my keys, a pack of kleenex, and a pair of socks (I was shoe shopping!) above all that you see in there. (Yes, including the water bottle!) So yes, quite roomy. Most would trade in that water bottle for the make up so I'd say it'd work for MOST people in terms of size.
(And sorry for the caustic flash on the second. Without the flash I couldn't see what was inside).
