In a Man of Steel universe, how would you realistically and logically explain the origin/reasoning behind Flash's costume in a live action movie?
Superman- Kryptonian armor
Batman- Custom WayneTech military-grade armor
Wonder Woman- Amazonian armor
Green Lantern- Oan uniform
Cyborg- Apokoliptan/Star Labs machinery
Flash? Where did he get it? How is it so resistant to wear and tear? Could he realistically make it himself or afford the materials? Why did he decide he needed it? Can it look good in live action?
