My Twin sister and I have been big fans of Venom and Spider-Man since we were very young and now that we are into cosplay we've opened a whole in window on our Marvel Fandom. Only problem is were kinda lost on what to make out of. I've heard some people make it from PVC and a handmade spandex suit. We want to make replica's from Spider-Man 3 the movie. I've asked some forums and looked up a few but I get ignored when I ask.

Do you know where we can get a cheap Spandex Suit on the
internet or at a store?
Should we use PVC or Latex for detail?
What do you suggest we do for the Venom Mask?

Your help is greatly appreciated.

Search Zentai on ebay, you should find a load of full spandex bodysuits

Thanks, I'll do that

I just don't know if latex would be good for the
webbing on his costume or whether it would hold up
for very long. I'll just test I guess.

I was thinking maybe I would use this suit I found awhile ago. http://cgi.ebay.com/Black-Lycra-Spandex-Zentai-Unisex-Catsuit-All-Detached-/250702847317?pt=LH_DefaultDomain_0&var=&hash=item800f75be88
Spider-Man's gloves and boots are seperate so I thought this might be a better choice. But it's kinda lost on me
when it comes to the details.

You could get a long sleeved turtle neck - make sure it's a good fit, then glue craft foam or upholstery foam in the shape of Spidey's various muscles, then, making sure you place it on a duct tape dummy, either latex or sew the fabric on top. You'd have a home made muscle suit.

The reason for the dummy is that latex shrinks after it's initial application, if the turtle neck is on the dummy then you know for sure that it'll still fit you.

you can buy 3d fabric paint. if you have a good hand, it could look really effective.

Ah yes 3D fabric Paint, my enemy.
I'll put it on my to try list of spidey detail.
Thanks
