Japanese Heroes: Woman Saved From A Moving Train.

Dozens of Japanese commuters bravely pushed a 32-tonne train carriage away from the rail inorder to free a trapped woman that accidentally dropped into the 20cm (8inches) gap between the rail and the train.
 The act of heroism began when a public announcement of the incident was broadcasted, promptly inviting over 40 people, both males and females, to join the train officials to push the heavy train away from the rail, just in time to help the woman in her 30s' perform a save.

I guess that you don't need a body-fitting costume to save someone...what you need is a good heart.
