I want a white leather one, and I have a red/horn one. Actually, I'm thinking of selling the horn one, as I really need a smaller size (now I sound like shopmom) and I'd rather the all-horn version.
they have a poitron one at my store, GT....my SA wears them, and they DO discolour, but she wears them day-in day-out. She has a blue jean chien cuff that looks BLACK!!!!!! Seriously, I asked her what colour it was, because I didn't recognise it!
To stop it from discolouring, you could give it a wipe with a baby wipe after each wear - that's what I do with my white leather cuffs.
