That’s like mixing peanut butter and chocolate except the peanut butter is something called Jiff.
What can I say? She got really into the lore (old EU too, obviously), had red hair at the time, and you can make a reasonably accurate Mara Jade cosplay by just reaching into her closet and pulling out four or five random articles of clothing. It was kind of a no-brainer when the “What SW character should I dress up as?” question came up.
