Basic Robe

I finished my robe base today.  There will be a ton of detailing added to this, but this is what it's starting as and the shape, etc.  I haven't figured out how I want it to do up in the back though.  The pattern I'm using calls for a ribbon tie up type thing....but I'm kind of leaning towards doing a hidden zipper.  Also, I'm contemplating taking it in to make it a bit more fitted and to make the bottom a tad less wide so that the additional pieces won't get lost in the folds of fabric.

Also, to give you an idea of how the shoulders look, size-wise, as compared to me and the robe:
