Just because you can portray a realistic rendition of these characters, don't forget there is magnificent value in satirically inaccurate cosplaying. If you watched the Big Bang theory last night, where the fellah who owns the comic shop is talking about how his girlfriend puts on her plus-sized Wonder Woman outfit and beclhes that he has to come ride her invisible plane...
It has to be more fun to make the fan boys and fangirls wretch and vomit rather than swoon.
However if you want to be picture perfect there's always tactically applied padding to consider?
Besides the hardest thing about Seven is getting your hair to stay clipped back like that for the duration.
