1) Before Icarus joined an academy squad he was often seen wearing jeans. Due to his wings he usually wore a tank top or simply no shirt at all. He favored boots for footwear but often went barefoot as well. Finally, he would carry around his guitar at all times.
2) As part of the Hellions squad, Icarus wore the standard pink body suit with light purple highlights which covered his torso down to his feet. The uniform was completely sleeveless and Icarus sported an open dark purple vest revealing the X symbol in the center of the chest.
3) When Icarus switched to the New Mutants squad, the color of his body suit changed to their standard yellow and white with gray highlights. The yellow upper half framed an X symbol on the chest and created an additional X symbol towards the abdomen. He was still completely sleeveless but the otherwise full body suit extended down to his yellow soled shoes.
