You do realize that someone could buy you an optifine cape, then have it transferred to their account. Not to mention, they will control the color and other stuff associated with it. I wouldn't recommend buying this, but you can if you are willing to take the risk.
They can just move the cape to their account after they purchase it for yours, and get the stuff you listed.
