I keep all of my old Halloween costumes lmao.... my favorite one is my Yuji Itadori costume from last year, so I guess that. I bought it from Amazon. (Also random, but this guy in my neighborhood hands out merch/figurines to ppl dressed as anime characters and he's literally SO cool. He gave me a Sukuna figurine. I despise Sukuna, but it was still a really neat thing to be gifted by a stranger.)
