That's a tough call. I am immediately drawn to the green (I love green, and it's more unusual), but the b/w is pretty classic and will go with more, IMO. They're both great though!

get the green!!! It is a very versitile (sp??) color and will go with a lot. I have a green bag that same color and it is great! I use it all the time.
