Yes. All costumes in the original Wii U game (and DLC costumes) can be collected in this game. They're all scattered across Adventure Mode (Link's Goron and Zora tunics, and Link and Zelda's Skyward Sword costumes are on the first Adventure Map, Boss costumes in the Rewards Map, Master Quest costumes in the MQ Map, Twilight Costumes in the Twilight Map, and Mask Costumes in the Termina Map).
