1) Cerebra's main uniform was a mixture of green and black fabric. She wore a basic black bodysuit for her lower body, which gave way to a green one-piece style going upwards, leaving her upper chest, shoulders, and arms exposed. Green leggings covered most of her legs, occasionally ending with black or gold boots. Occasionally, she wore a shawl or headscarf draped over her shoulders and held in place by ornate gold clasps. She also accessorized with a traditional gold belt with red 'X' buckle, and wore green gloves complimented by gold wristbands and armbands.
After losing her powers and her ability to walk, for a time Cerebra used a vintage yellow hoverchair based on the design originally employed by Charles Xavier. [X-Men 2099 #1]
