I just happen to like anything in khaki, and with crimson, wow; but I do have to say that I saw my son's teacher today and she has that bag in the black you posted. It is gorgeous. Oh, :shame: and I peeked inside when I was standing over it (it WAS opened) and she had the matching goodies. I think that tote is fabulous in any colour; the shape is great and it had alot in it, but it didn't look bulky to me.
I will be no help because i love either of those, but i say if you really want a black bag than you should get it, plus it won't show dirt like the khaki one...but whatever you choose will be beautiful!
