Whats the point of the costume? I mean, Batman uses it because he knows that people are scared of Bats, Captain America represents the nation and thuus wears a flag, etc. Or is it just for the look?
Well, for the costume, a lot of it is about protection. It's a -serious- lifesaver. Just off the top of my head
-It absorbs energy blasts [protected him from Dr. Doom's full-stop photon beam, only the magical portion hurt him, since he doesn't have magic protection; also helped against Jessica Drew's venom blast and Speedball/Penance's energy attacks],
-It absorbs blunt impacts [let him shrug off a full-force kick from an angry Spider-Man who was legit trying to cripple him because he mistakenly thought Task kidnapped MJ, also recently let him shrug off a hit from Sebastian Shaw that broke the wall behind him].
As for the mask, originally it was just to hide his face, and he liked the design. It's also sometimes armored, as evidenced by Moon Knight, when he tanks a point-blank shotgun blast to the face without a scratch.
As for the rest of the costume, it's supposed to be a pastiche of different superheroes, just like his powerset. The boots are Captain America, the cloak is Moon Knight, the skintight bodysuit is Daredevil, and the colors were his own personal touch.
His 2010 mini fleshed out why a skull, though, and I really like this origin:
