Nintendo has revealed a new costume for Mario in Super Mario Odyssey. People can now dress Mario up like a conductor. This means a whole new wig and suit for him to wear, provided you have beaten the game and have enough coins to acquire it.
This Super Mario Odyssey costume appears in Crazy Cap stores after the game is beaten. You can get the Conductor Wig for 500 coins and the Conductor Outfit for 1,000 coins. Like the Painter Outfit available after reaching the Luncheon Kingdom, this costume is based on art from Mario Paint on the SNES.
Super Mario Odyssey is available for the Nintendo Switch. In case you missed them, Spewart and Hariet costumes were added in August 2018.
