Texture wise, it's beautiful and it really does Lacey justice but it refuses to be white. I've tried using Mane n' Tail Spray n' White on it, I've even left it in for 15 minutes! I don't really like leaving it in that long because then the middle of her tail which is pretty white, turns purpley. Her tail is also pretty short so I can't just trim off the really nasty parts.
Any tips to help? I might be braiding her tail so she'll lift it up super high and cute but even if I do I really want it to be really white.
And believe me, if I get her tail white it's going to be braided and wrapped to the hilt until next saturday!

I've gave her a bath yesterday so her body is whiter that in that picture and her legs are cleaner, haha, but her tail...
