I'm also posting it here because.. well, it's a texture pack.
Basically, I think the undyed layer of leather sucks. It's like a new toy that you were given and the next day someone comes in and steps on it. I don't see how people are confusing blue leather with diamond, but this undyed layer stuff is not the answer. Here's a tweaked texture pack to remove the layer. This will only work for those who have it installed (having it installed will not make other people see you without it, unless they too have it installed). The only thing it does is remove the layers.

I kinda hate the undyed layer to feels so dull unless dyed.
