Jedi Outfit For Halloween

So I brought a Jedi outfit, an Obi Wan Kenobi replica, specifically, for Halloween. I brought it from jedi-robe.com and it costed £200.

I put it on and it looked good, however, I can't seem to get it completely right. Is there a tutorial out there with someone demonstrating how to put the specific outfit I have... on? Or does anyone have any tips for me in terms of adjustments? I want to get it near perfect for Halloween and also some pictures! My Obi-Wan Kenobi light saber with a removable hilt will be arriving tomorrow, too.

Here's the outfit (I have the dark brown robe):

Here is some ideal pictures of what I want it to look like:
