What are you talking about? The man is cosplaying Clark Kent..That's a SIGNATURE pose..He IS wearing the cosplay directly..it's not a Superman cosplay it's a Clark cosplay when he is in mid change. Just about everyone on earth knows this pose..
Also, Emi, what mask? There is no mask....Not only does Superman (or clark) wear a mask, but he also does not have one in this picture anywhere that could have been "Accidentally off"..So I have no idea what you both are even talking about..
And he was not "keeping the suit on to be modest"..Does no one know things about Superman anymore? That's a shame..
