Shaak Ti costume?

[feena]

I have always wanted to make a Shaak Ti costume. Not necessarily for me, but instead for my younger sister (who looks like an older sister. -_-).
She loves the idea, but wants specifically to do the version from The Force Unleashed video games;

now, normally I would be like- "Oh no, girl. You know Dad would KILL me if I made you something like that."
However; I myself already have a Maris Brood costume completed and honestly I would have so much fun making this.
Now, my question is,
How on Earth am I supposed to make the horns?
Any ideas?

To have it fit properly.I'd suggest making a head cast.You would need something light plus have the support of the other "Lekku" to hold it on.you can try wonderflex.Then put your paint then lacquer it .I'm using wonderflex for my husband's wookiee underskull.You can mold it by to any shape you like by heat gun.My only concern would be is direct sunlight(Heat) That's why I'm suggesting the lacquer.Wonderflex is on a cosplay site it isn't cheap either.you might also try fiberglassing it too. You would probably need a light underwire system to fit on your head and support your lekku,or do like I'm doing use the wonderflex as an underskull the dip it in latex.Just suggestons,but I would do the head cast for certain.
your horns you could make out of super sculpty,mold it,make sure it conforms to your head on the piece. bake it,paint it,
lacquer it.then you need some.face adhisive.Costuming shop,or on line.

Oh, wow. Thank you so much.
I was so worried about the head piece being too heavy for her. I do, actually, have much of the materials you mentioned, so perhaps it wont be nearly as costly as I thought. My main concern now is how to make the "lekku"...

I would try the wonderflex it is light,malliable.Try to weave a light wire frame for your lekku. place the wonderflex over it

Really? Wow that stuff sounds awesome. I've never used it before, so I'm a little nervous.
All the tutorials online were telling me to use liquid latex, but since I'm VERY allergic to latex that's out of the question.
Thanks so much for your help.
I'll post some in progress pictures when I get it started.

my only concern is heat I would try to lacquer it so it would hold it shape.If you are going to use this in a controlled enviroment(Out of direct sunlight) for long periods of time.I would still lacquer it,but get a "matte" finish you don't want to get your lekku too shiny I woudn't worry about it as much
Since you are allergic to latex.you could try the fabric method,but they don't look as accurate,and tend to be lumpy.

I've seen some very well-done fabric lekku, and I think it really matters what you use for the stuffing. The finer the stuffing, the less chance of lumps. I've never done it, but a local club member made two twilek costumes last year for D*C, so I'll ask how she did it.

I've never seen that version of Shaak'ti. Very video game-ish.

Her lekku are a bit stiffer than a regular twi'lek. So wonderflex could work fine for the 'horns' part at least. Be very careful about having too much weight on them. They may not seem heavy, but it adds up for a costume you're wearing for a few hours.
