Yeah, the DLC is finished (most likely) and they probably have all the items all ready created and implemented. So if they were to stop everything, go back, design and add
another item... there would be another delay. It's a good idea, but like most of the weapon and armor suggestions that have been buzzing around, it's too late.
Like Expresate said: if you're on a PC you can persuade a modder to add it in, or mod it in yourself!

However, if you're on a console like me: then weep quietly.
Edit: In my personal opinion, I don't like the bagginess of the pants. But that's just my two cents.
