Twi lek Costume help?

My fiance is wanting to cosplay with me at the next con we go to, or just for a costume party we go to. She wants a Leia Gold bikini. Which is fine by me lol. But we live in Canada and it gets cold come October. So i suggested a Twi lek. I know that's not much better for clothing. But if its a cold night she can change the style of cloths for her twi lek costume to suit the weather.
I've looked all over the web and can't find anything good on how to make the lekku or what a good body paint is. If anyone has any good leads that would be great. I would like to stay away for the pantie hose idea some people have had as it looks to fluffy and out of shape.

i personally cant think of anything but good luck someone has to know something

You should definitely check this website.

I too have been researching a Twi-Lek for my girlfriend for next year's SDCC and CVI. I found Pam's web site a few years ago and it her information and experience has been a huge help.

This is also an excellent resource:
