No other pets, sadly. Camie sounds interesting; when I was younger I wanted a chameleon!

I've got a lot of other cosplay projects going on right now, so if I went I'd probably just do ears and horns and make some cool staff or prop, and I'd wouldn't do goat legs or hooves. I'd probably just wear a hoodie and sweatpants and boots. Plus, I don't think I'd use the hooves & legs often enough for it to be worth the cost of the fur. I'd definetely wear a cloak, as actually making a cloak is one of my cosplay projects that I'm working on now, but if it isn't finished by then I'll probably use one of the storebought ones from old halloween projects. I might see if I can make something out of leather, although it's pretty difficult to work with. I usually get my leather from thrift shopping and buying leather items and then taking them apart to use, so it would also depend on if I could find enough.

Yeah, I definetely want to go, but I dunno if I'll be able to... I've got a lot of things I'm doing this summer and I'd have to look at my schedule.

Yee, I love it when people as for pictures!

Hmm, I don't read much anime, but I have heard of Sailor Moon. Himiko Toga is way cooler than Sailor Moon though.

Kass would be a difficult and expensive costume; just from looking at images, for a good costume it would be a lot of work. The mask/head wouldn't be too hard. I've done stuff like it before. What you'd want to do is look up "therizinosaurus jurassic park mask" on Google. You could potentially paint one of those and decorate it with feathers to look like Kass. The rest of it, though, would be pretty hard. Incorporating feathers with a costume is difficult, if you use the type of realistic-looking feathers found in a craft store it would be expensive and hard to make and fragile and impossible to wash. What I'd do is use feathers (you could possibly make cloth feathers using minky and a little stuffing to make it washable) for the little plume on the mask/headpeice, and skip feathers for the rest of it and just use fur instead, because most of the rest of the feathers are so short that they aren't really visible as distinguished feathers. But you'd need to make pretty much a full suit, which would be a lot of work, plus you'd need to make the clothes, although you could potentially find something online that looks similar to Kass's clothing that you could buy. You could also possibly buy a Kass costume, but for a good one it would be pretty expensive. Proper costumes that look good and use fur or feathers could be 800+ dollars and would have to be custom-made by a cosplay-maker.

Hollow Knight would be a lot easier. 

I'd make the mask/helmet out of magic model, by making a large ball of newspapers in the size and shape of the helmet. I'd try to get it as smooth and symmetrical as possible. Then I'd mold the magic model around it, in two separate halves that I would then glue together. After it's dry, if the eye-holes don't look the same I'd use an exacto-knife to save them to the same shape. It doesn't matter if a little newspaper gets stuck to the inside of the helmet because it'll be inside. After glueing it together, I'd paint a coat of modge podge onto it (making sure to fill any cracks with the modge podge) and then paint it white. For the eyes, I'd get some fine mesh (you can probably find some at your local craft store(s)) and use a sponge brush to paint some of it black, then glue it in behind the eye holes. For the horns, I'd make them after glueing the helmet together but before modge podgeing and painting it. I'd take some aluminum foil and mold it into the shape of the horns, then cover than in--you guessed it--more magic model. After all that is done I'd use painters tape or masking tape to tape more newspaper into the empty space in the helmet so that it stays in the right position.

Then you'd just have to wear all black clothing and buy a cheap cloak and cut it up into strips. For the sword-nail thing, I'd make a cardboard base shape, and wrap it in duct tape and use sharpie to decorate it, although if you wanted to be really fancy you could coat the cardboard in more magic model and then you could actually carve the designs on it into the magic model, although you might want to score the cardboard first or use glue to help hold the magic model on. I would probably go for just duct tape and sharpie, though, unless you're confidant in your magic modeling skill.

Huh, now I kinda want to make a Hollow Knight costume.

Also, I can't wait to see the drawings!
