Can someone explain Superman's new 52 outfit for me?

I'm reading through new 52 superman and i notice that his suit comes on and off like its appearing out of thin air or something, did i miss something here?

@wolverine1610:

It's a bio-suit.Made from very small nanites that concentrate on the S symbol on superman chest.When superman needs to wear the suit the nanites expand and form it.It can take a variety of forms as seen in Action Comics.

It is an ceremonial armor it can't probably used in battle.

ooooh, well that makes sense. i havent read everything from superman new 52 yet so i was like hold up now. i thought it was like the old superman movie where he jumps a building and it just appears
