M'k, replying to both of these in one post, for convenience.
Top reply: I… am assuming that you’re talking about Mituna? Unless you also would like to be God Tier Roxy, which is cool, too. Double the Roxy, double the fun.
Anyways. Dood. If you go as Mituna and chill with me, I’ll love you forever, because all the awesome. Do it. Be the Mituna.
The hardest part would most likely be the helmet - the bodysuit would be somewhat easy to throw together, though; you just need a catsuit and some fabric paint that can deal with stretch materials w/o cracking. Either that, or you could just sew on some stretch fabric made from the same/similar material to the catsuit.
As for the helmet, though.. That part’d be a bit of a bitch, potentially… There’s some tutorials for it, but.. It may or may not be a slight pain in the ass.
Bottom reply: Yeah.. It’s kind of a pain in the ass, because there’s SO MANY THINGS TO BE, but.. not a ton of time/too many options. That’s kinda why I ended up doing a coin toss on it; I’m pretty sure I’d just sit around debating what I could or could not do, which’d kinda just screw me over when it came to getting stuff done. I don’t wanna do everything last minute like with Latula - while Latula turned out, I feel like that was mostly luck, and I’m pretty sure I totally could done that way better.. good news is, I can fix up whatever I didn’t like between now and the con, annnd I can potentially have another cosplay for one or two of the days. :)
