"Clothing resembles the gi Goku wore when training with Whis in Dragon Ball Z: Resurrection ‘F’."
The Whis Symbol Gi's design is partially based on Goku's Turtle School uniform though is somewhat lighter in color, lacks a inner shirt, and features a slightly different obi. Though originally created by Whis the Gi originally lacked a symbol, but while sparing with Goku and Vegeta on Beerus' Planet, Whis playfully signed the front of the gi with his symbol showing off his superior speed. Goku wore the gi during his training under Whis and during his confrontation with the revived Frieza in Resurrection ‘F’ and Dragon Ball Super.
Goku also wore this gi during the Universes 6 and 7 Gods of Destruction Selection Martial Arts Competition in Dragon Ball Super.
Video Game Appearances
In Dragon Ball Xenoverse 2, the Whis Symbol Gi returns as clothing options for the Future Warrior (Xenoverse 2) which can be obtained by transferring it over from Xenoverse or its pieces can be obtained in Parallel Quest 76: "Eternal Rival". Due to the lack of an inner shirt, a bra-like top appears when it is worn by females in both games.
