I suppose. But there's a limit. For the past... 2 years? Every single masquerade has had like a Naruto x Sasuke AND/OR Sasuke x Itachi theme. At least one. Usually more. You get tired of seeing those. Death Note too... Maybe cus L's costume is just jeans and a white shirt with black rings under his eyes? But since Misa dresses like a loli-goth, you can only imagine how many of those there are @.@ I thought nobody liked Misa but apparently everyone loves dressing up as her
