C.C. has long light green hair and gold eyes. She wears a variety of outfits, which change depending on the time and situation. In the first season she mainly wears a white straitjacket bondage suit, which the Britannian Empire had used to restrain her for tests prior to the series. According to the 2007 "Code Geass" audio drama, C.C. wears the bondage suit because she feels she isn't free, and is a slave to the world. Her main outfit in the second season is a modified Black Knights uniform, which is long, black, and has a red sash. It has gloves and white undergarments. She has worn Lelouch's own clothes, including his Zero outfit, to serve as a decoy and save him from situations.
