メタファー：リファンタジオ 「ペルソナ５」秀尽学園高校制服&バトルBGM＆バトルジングル セット - レビュー・評価・同時接続数

Dont bother getting this or any other costume packs, the costumes are rarely visible, they only appear in dungeons and battles, dont even appear in safe rooms or cutscenes, not even cutscenes in dungeons.

Heads up, this DLC is not implemented the way P5's was, where you could pick battle themes separately (or put them on shuffle). Instead, the battle theme always matches the MC's outfit. Also, the outfits are only visible in dungeons and in battles, but not at other times. Product page doesn't mention this so I'm mentioning it here. Looks like someone on Nexus made a mod to make the DLC music in Metaphor work more like P3R's. Go look it up if this sounds like something you're interested in.

I do not recommend any of the costume or music DLC for this game. Atlus has not learned any lessons from either Persona 5 or Persona 3 Reload. You cannot set your music at will, nor create playlists of different music to enjoy. Your MC's costume determines the battle theme. This is idiotic and Atlus has been getting flak for their idiotic music practices for years. I thought they would have learned with this game based on actual gameplay improvements, but they have not. If Atlus simply changes this and adds the same kind of music playlist feature recently added to and improved in Persona 3 Reload, then I would probably recommend them because the outfits are cool and music is banger.
