Nick skinning trouble?

Ok im making my own personal skin and using Nick. He wears a suit, And i can paint the top layer of the suit, But underneath it is still white, I cant work out which bit of the texture sheet is that part, Ive even tried pasting the whoel sheet the colour i want it but still the colour underneath the suit is white like the original texture… Could anyone help?

Oh you mean inside the jacket? It is the white outline around the blue part of the shirt.
