Costumes are obtained in different ways in the original and expansion to Higurashi Daybreak. In the original, you need to beat the game on Story Mode, and the successful completion will unlock the costumes for the character you played, meaning you would need to complete story mode as every character to unlock every costume. In the DX Version, all the costumes are already unlocked.
For the original: Hold the lock button while selecting the character (キャラクター選択時にロックボタンを押しながら決定してください)
For the DX Version: To change costume, press the left or right keys when selecting Weapon/Hypermode on the Character Select Screen.
