There are robes yes but there is not 1 iconic jedi robe/outfit in this game sadly.If you want to look like they do in the movies like most of us that is not possible.And the really sad thing is one can not take down the dumb looking hoods on any of them.
EDIT: This is a picture of an Alderaan guard. http://i.imgur.com/QEkUX.jpg
Thats the closest thing you will come to a iconic Jedi outfit in this game.
Maybe they will actually give us star wars outfits in the near future(we can dream)
