Quicksilver has wore a plethora of costumes during his career as both a hero and villain.
The classic costume Quicksilver uses in his first appearances varies, sometimes it is blue and some others green. The costume is most likely made of spandex, and sports a series of white lightning figures over itself, a big vertical lightning across the chest and other smaller ones on his wrist and legs.
During his tenure as an a member of the Serval Industries' sponsored X-Factor, Quicksilver was given a uniform, with a similar scheme to that of his other teammates, which consisted of a golden yellow garment with a grey section that ran from his lower torso and back, also covering most of his right arm.
As a member of the second wave of the Unity Division, Quicksilver sported a more technologically advanced suit, along with some googles to protect his eyes while running at high speeds.
