And there's always camelcamelcamel to equalize the equalizer.
Most work uniform "suits" are clearly uniforms. They're just close enough to suits that they could be described that way... if you really want to. I think Obama's point was that his skin made him invisible no matter what he was wearing- that black skin could make even a good suit look only "suit-like" because as a black, he obviously wasn't a customer.
But I didn't see the clip of him saying it and I haven't discussed his motives with him, so I could be reading it wrong. It seems reasonable to me, though.
