Here's Sam Flynn's entire costume from Tron Legacy to save you from searching for the few photos there are floating around the internet.
I made it as accurate as I could, Sam's costume is more complex than Quorra's, although it is completely symmetrical which is something of an advantage.
I think the proportions on a few things are slightly off, but all the details are there.
The connecting points means where the shoulder armour attachs to the chest pieces. On the actual costume it's all one piece.
Also keep in mind that the pieces on his torso are very narrow, they don't cover his entire chest or back and there are no side panels. It seems to be attached directly to his shirt.
If you need a trade sketch/reference sheet for other Tron Legacy characters just leave a comment below. I might do ones for other movies if I have access to decent photos.
