Dressed my daughter up like a Borg for Halloween one year. She was in high school. Wove aquarium tubing filled with glow-in-the-dark paint through her hair and painted her skin with metallic eye shadow. Finger-less gloves with clock gears sewn on the back. Black leggings and biker boots. (Outfit wasn't quite as tight as Seven's though.)
Coolest costume I ever made.
