So the basis for Widowmaker is that she’s top tier assassin who is emotionally absent and conditioned to be the perfect operative *.  For some reason her outfit doesn’t seem very much like those belonging to male characters from similar archetypes (all of them being the “best of the best”).

Which is kind of a shame, because I did a mock up of what she might look like if she took her clothing pointers from the more established members of the archetype and personally I think she still looks pretty damn sexy.
