Rubber, leather or plastic?

leather for sure

mmm, never tried any at least not for a costume. If I had to choose it would be leather, seems much easier to breath in.

um, none of the above?

leather out of those three .

Oh god, I couldn't do either one.  I'd honestly go with spandex over those three, lol

Definitely leather. I'm a class act.

How about just using bin bags and sellotape?

Rubber would be gross, you's have little puddles of sweat trapped everywhere underneath your costume.   
 
I would want mine to be made out of smart textiles, lightweight but relatively resistant to harm and also with some moisture wicking, and if it came in a dark grey and purple (with maybe some aspects of pink in there?) that would make it just awesome.  

street clothes for me
