Superman and Supergirl Costumes

I can't remember the first time when I watched movie Superman, but the image of superman is impressive. The image originates form DC Comics. He usually wears a blue costume, red cape, and stylized red-and-yellow "S" shield on his chest, like this:

Some said it looks like he likes showing his red briefs. It is a strange habit. Last year, there is movie called Superman Man of Steel. This superman's costume has changed. It turns to deep blue costume,which I like better.

Besides superman, supergirl appears, which I don;t know it before. Supergirl is superman's sister? Maybe we need read some DC Comics. About costumes, she also wears a blue costume, red cape,  and stylized red-and-yellow "S" shield on his chest, but she does't show her knickers, which I feel it is a pity.

Every coins has two sides, where there has justice, there has evil. No evil superman, but has evil supergirl. 

From that, we can learn do not offend woman.
