Maul is a badass with a double-sided red light saber but more than that, he has super cool clothes. I'd purchased the main outfit (including the mask and boot covers) along with a cloak. I had to buy the gauntlet gloves and turtleneck. The cloak turned out of be completely inadequate and Maul's cloak is flowing, voluminous, and awesome so I decided to make my own, placing all my modification efforts there.
I bought a bunch of black linen fabric at 50% off and used my bathrobe as a pattern. After sewing it together, I then sketched out the hood but made it huge (Maul's hood drapes down in the back even when he's wearing it) then sewed that on. Connecting the hood to the cloak was a challenge but I got it to work. I noted that Maul's sleeves were very long, almost to the floor, and split on the underside so I had to add more fabric to the already very long sleeves to make them look right.

The company has a tradition of allowing the employees to bring in their kids for Halloween trick-or-treat and a bunch of fun activities for the families. When the kids came through I had to take my mask off because I kept scaring them. Hell, I was scaring some of the adults.
We're already talking about next year and "Alice in Wonderland" has come up as a possible theme. I would love to be the Mad Hatter again (I did a really great costume of the Hatter years ago) but if someone else wants to be the Hatter then I'll be Mock Turtle. Of course.
