I feel you pain (you and the person below this, lol). When I did Shippuden Gaara I was a detail whore about it, and now I think I'm a bit bitter about the zippers on the sleeves, because to change that one thing I'd have to pull my lining out and redo it...and I don't want to. T_T

In the end, if you don't want to, I wouldn't worry about it. Personally I tihnk it was just an alteration for that particular bit of art, because before that it never looked like the white could be quite that long. >.>
