I wonder what style of costume they will go for?
Will she have a tight latex costume like Silk Spectre from Snyder's Watchmen or will they use one out of the comics or an armor version resembling Faora.
Here are some costumes I like.
Pants version from J. Michael Straczynski's short run back in 2011.
Armored Fan art version (artist page here http://nebezial.deviantart.com/
The upcoming Justice League War movie costume
So many I like. Decisions, Decisions
I'd bet some form of the pants costume... That said, you could also take not account the outfits from MoS as an idea of direction. Kevin Smith was shown a pic of Afleck in the batman suit by Snyder after some yahoo MoS q&a he moderated, and said its nothing like has been shown in the movies so far. He aid it was very much like a particular comic style, buy it was beeped/censored in the Hollywood Bable-on podcast so unless you were there you don't know specifics.
