I need some help figuring out what to cosplay as for Otakon Vegas this year. I am torn between Misa

I need some help figuring out what to cosplay as for Otakon Vegas this year. I am torn between Misa Amane from Death Note and Haruhi Fujioka from Ouran High School Host Club. I would love to cosplay as many other people. However, due to the holidays just being over and spring semester starting on January 20, I am down to my last couple of weeks to put together my cosplay. I will only be going on January 17.

I currently have dark brown/black hair and bangs across my forehead. I am only 4'10 but height doesn’t really matter. I’m only saying it because some things I have to buy/make smaller and alter it. 

If I were to be Misa, I have most of the outfit and hair taken care of. I may take out the blades only because I have no idea if I’ll be able to have someone help me make them (I have shaky hands so I cut myself easily). I would just need to mail my Death Note from my previous home in California. However, I would also have to buy knee high socks online (thigh highs are too long for me). I would not buy a wig because I do not have a place to put it to keep it nice. I got her personality pretty much good and I love her style. 

If I were to be Haruhi, I would be the version of her in Episode 16 when Hikaru takes Haruhi on a date. Again, I am not planning to buy a wig so I would not be the normal version with her short hair and Ouran uniform. I’d make her costume but it would not be too hard. I can buy all the materials and sew them together. I would also wear headphones around my neck/on my ears and I may walk around with a thin white blanket or sheet. It will be cool outside so even though I’d be wearing sandals, the blanket/sheet will keep me warm. I absolutely love the scene where Hikaru finds Haruhi in the church and he puts the headphones on her to keep down the sound of thunder. I love her and all the characters from Ouran. It’s become one of my favorite animes.

I love both of the characters and the shows. If I can’t decide by the end of this week, I’m going to go with Haruhi but I’d like some help if you would. Thank you!
