• If you collect the W Emblem badge from Charlieton, the traveling salesman, equip it to change into Wario's clothes.
• If you collect the L Emblem badge from Poshley Sanctum, equip it to change into Luigi's clothes.
• Equip both the W and L Emblem badges to change into Waluigi's Clothes.

In the game, there are two Emblem badges. They are the W Emblem, and the L Emblem. Finding these badges is tough. Equipping the W Emblem will make Mario use Wario's Costume. Equipping the L Emblem will make Mario use Luigi's Costume.During Chapter 4, Charlieton (The BIG guy in Rogueport Plaza, South of the cook's house.) will sell the W Emblem for 360 coins.

It is rumored that equipping the W and L Emblems at the same time will unlock Waluigi's costume, but it's a rumor, so don't get mad if it DOESN'T work.
