Reference Pic...>>>

Okay... So her costume is all shiney. So I was thinking maybe Strech Vinyl? I've never worked with the stuff but I've heard that cuz it's strechy it's difficult to sew and stuff. >_< Any fabrics you guys would sugest? Thanks!
I also can't fing a pattern for a leotard anywhere!! Does anyone have one that maybe they could show me? Like a site or something? I dunno, maybe I'll be able to find one tomorrow when I go to the mall but I kind doubt it. Anyone please? ._.
And for the headgear... What should I use? I already made a test-like one yesterday and today and it looks HORRIBLE. *swt* I can try to post a pic later. I really didn't have any stuff, so I had to go to walmart and WOW, that didnt have anything mostly I could use either. -_-;; So I ended up taking that thick, foamy posterboard, cutting the shapes I needed and covering them up with felt. :\ The yellow things on the side i covered with that Crayola clay foam stuff. ANyways, it dosnt look right. And I connected the parts that stick out too high, they're like right above my ears and not covering them ._. Ah well... maybe someone can help me there too? >_<
I also need a wig. >_> I can't find one that fits my needs well enough. D: I found one that I could style to look like her hair but it's on backorder... and I kinda hate waiting. <_<;; *sigh* There are wig sites, but they cost more then the regular wigs cuz they style them too. I can style the wig I just need it. :3 Are there any sites that sell them besides cosplaylab.com and the one that you can find off of Katie Blair's site? Thanks!!!
I'm so sorry this is so long... but I really want to make this cosplay look good. I might be able to go to one in PA next month if my parents will take me. It'll be my first... kinda scared but I know it'll be totally awsome. ^_^ I wish i could go to the Sakura Con but I can't, it's WAY to far for my parents to take me O.O lol... This is when I wish i could drive.

Thanks again everyone. ^_^ Sorry I'm such a newbie at this ._.
