Plenty of people cosplay as Link, star of the Legend of Zelda. Some people do it really well. Few, however, can ever seem to really match the appearance of the little guy. Probably because he's a small, cartoon-like boy with giant ears and huge feet.
Cosplayer Amouranth has given it a damn good shake, though, managing to not only look a lot like the more recent iterations of Link, but find a horse that does a mean Epona to boot.
