I think the black is the best choice. The white will become filthy, after all it's holding money.... the blue might clash with many of your bags! Go for the black, it's classic.
I'd go for the black, but I carry the same wallet all the time, and don't switch out. If you switch out your wallets, go for the blue or white (though the white will get dirty quicker).
Just went to the LV store which I love the black is nice for me the blue screams blue. Just depends what you are going for, a classic wallet or something thats fun. I would vote black...LV lasts forever black is a classic.
