I see this as being a better addition to the game than archetypes. This is because any archetype makes this game look as old as it really is (2003), and thats not what we're striving towards. If the implementation of this feature is not as hard, it can enable players to continue not using archetype, enable lightmaps, and not be hugely disadvantaged just because someone decided to wear white clothing, which are free for all to use.
I don't personally agree that blending clothing should be a valid strategy to make yourself harder to aim in a game like Gunz. In this game, your movement is what makes you hard to aim, and not what you look like.
