Cassandra Sandsmark has worn quite a few costumes after taking the mantle of Wonder Girl from Donna Troy, the first Wonder Girl. When she took the gauntlet of Atlas and the sandals of Hermes to gain super-strength and flight, Cassandra's first costume was a cobbled together uniform consisting of googles, a black wig, a bomber jacket, a black Wonder Woman symbol t-shirt, red bike shorts and white gloves and sneakers. When she had to return the magical Olympian artifacts, Zeus (king of the Olympian gods) gifted Cassandra with actual powers of flight and superhuman strength. Cassandra celebrated her new powers by tossing aside her wig, replacing her bike shorts with star-spangled blue jeans, and wearing a pear of metal gauntlets. After she became the leader of Young Justice, Wonder Girl got rid of the jacket and donned a black Wonder Woman symbol tank top, red star-spangled pants and black boots. After she became a member of the Teen Titans, Wonder Girl wore a new costume consisting of a red Wonder Woman symbol tank top, red leggings with gold stars, and black boots. Later Wonder Girl decided to switch her costume to a red-and-gold Amazonian eagle-emblem tank top and blue jean with a Wonder Woman symbol belt. When Wonder Girl learned that she was actually the daughter of Zeus and a goddess in her own right, her tank top became a red shirt with a stylized golden W emblem and she removed her gauntlets.
After the events of new 52, Cassandra was no longer Zeus's daughter, but was instead his granddaughter and Wonder Woman's neice (as her father was now Zeus's demigod son Lennox and Wonder Woman's half-brother). When she found the magical Silent Armor, she gained flight and superhuman strength. She donned a costume consisting of a red starry bodysuit with a hood, and golden gauntlets and boots. As she mastered the Silent Armor's powers, she gained a golden W symbol chest plate with a matching tiara and belt. Wonder Girl soon developed powers on her own as her Olympian heritage began to manifest. She then wore a red-and blue Wonder Woman t-shirt with a red bomber jacket with a black skirt over black leggings with golden star patterns and red sneakers.
