Wolverine was supposed to evoke the iconography of Cap, Spidey and the rest of the Avengers with his look. But they don't exist in Fox's universe.
I don't see many people asking for it to look just like the comics, but instead to see it adapted so it fits in the context of the films which there has been costumes already. Look back through this thread and you'll see examples of reasons why Wolverine could wear a costume and it be believable.
Also, at the end of the day it's still a comic book series filled with many aspects of the comic book. Wanting certain characters to look the part or wear costumes doesn't have to be about 'hiding their identity' or whatever. The other x-movies never put any over thought explanation to justify their costumes and even Origins had some form of costumes (just not particularly ones from the comics).
