I love the beige, my SA talked me out of it all together saying" it was to old of a bag for me" I think I need a new SA. she never wants a sale I swear! Keep the beige! I love it, it looks great!
It's been said many times but it really does look great on you and I think the size & shape of the bag suits someone of your stature. I am personally more a black bag person but even so, I'd keep this in beige and also get a black jumbo. Have you considered the medium/large classic flap? I never thought of it until my SA suggested it to me because I didn't think it could carry much. I'm a big bag person. But to my surprise, it's quite functional -- although I do have to pare down a little to fit everything in.
