So, I'm not going to go crazy this year, just trying to pick ideas I can make fairly simply at low cost from things I already own...the ideas I currently have are:

Nepeta Leijon (Homestuck)
...I look a lot like most people seem to imagine her to...all I'd really need for it is a tail, hat and coat...and paint & horns (if I don't do a human!stuck version)
Karkat Vantas (Homestuck) or
Mituna Captor (Homestuck) (genderbent)
this one, like Nepeta would be super easy for me due to my short/fluffy hair, I'd really just need a sweater, paint & horns lol but I'd have to bind to do a proper gender version...it's possible but uncomfortable X33 (this would probably be the cheapest way for me to go with a costume I haven't already used before)
CatWoman (Batman)
I'd need a hat/helmet and long-sleeve black shirt for this, but I think I can make due with other things I have...my hair's starting to get too long for it tho
Professor Trelawny (Harry Potter)
A skirt and I'd actually be able to pull this off lol I have some wefts I could add to a headband to create the crazy hair
Luna Lovegood (Harry Potter)
I've got a wig that would work for this and I've probably got enough quirky clothes :33
Hermione Granger (Harry Potter)
A wig, button down & skirt :33
Tonks (Harry Potter)
A wig...I could probably put the rest together from my closet
Witch
Oldie but goody :33 I really need a new hat but other than that I'd be great...I still have my sea witch costume from last year
Vampire
Again...I could do this from my closet lol I love Gothic style clothes, and have quite a bit of it
Black Cat
Not the Marvel Black Cat character, the animal lol I have everything for this one

Feel free to toss out any other ideas you may have and I'll let you know if it's something I could possibly do :33 If I do something that includes a need for makeup I'll do a step-by-step tutorial for it once I get my hands on the supplies!!

Hope you're all doing well and thanks for reading!!
