Looking like Altair: $1,000. Killing your Boss: Priceless.

You may laugh at this Altair replica outfit but anyone who can throw away over $1,000 to wear this to a single Halloween party demands your respect… at least, begrudgingly. The entire get-up from Museum Replicas requires dozens of parts including $240 boots, at least 3 layers of clothing, a $36 red sash (you could probably buy just this and wear a white robe and still be recognizable), and hundreds in pointy blades. You’ll be the talk of the office party for sure, especially after you assassinate your boss and then scale the copier machine with nimble speed and escape through the drop ceiling!
