This is hitting a couple of sites, but Entertainment Weekly got the exclusive. Seems a little photoshopped to me, but they are filming the TV series now, so at some point we have to see Adrianne Palicki in the uniform. It looks a lot like the version that was introduced about eight months ago in the comics except the black pants and boots are now blue. It's not bad. Better than most of the costumes that the cosplayers wear of the traditional uniform. What do you think?
UPDATE: DC The Source has also posted this, so I guess this is legit.
