Game Freak will distribute the outfits players wear in Pokémon Platinum as a limited-time free pre-order bonus for Pokémon Brilliant Diamond and Brilliant Pearl. Pokémon Platinum was the third game of the fourth generation of Pokémon games that served as a successor to the original Diamond and Pearl. Platinum had features and functions that weren't in Diamond and Pearl, which included the world of distortion and upgraded Gyms.
Fans were hoping that some of those Platinum elements would make it into Brilliant Diamond and Shinning Pearl. However, Platinum's clothing is currently the only thing in the game that is turning into new remakes.
To qualify for Platinum clothing, players must have played a copy of the game by February 21, 2022. The games will be released on November 19, giving players a three-month window. Players will also need to have an internet connection, but do not need a Nintendo Online membership. If players are logged in, they can obtain clothing from the Get Online option in the Mystery Gift feature in the Shining Diamond and Shining Pearl main menu.
It's the same way Game Freak handles The Baneful Fox mask in Legends: Arceus. It takes approximately two hours of gameplay before players can access the Mystery Gift feature and can change outfits as soon as they reach the Metronome Style Shop in Veilstone City.
