Heed the reviews.  This does NOT cover your butt in back.  It's not made to do that.  In fact, inspect the page and you will see how the model wears it in one picture - the front draping ends are tied like those Daisy Mae shirts we used to do in the '70's...  However, I ordered the colour Emerald and it is true to colour, and ordered one size up, which fits well (I am 5'10 and wear a medium). I will wear it anyway because it really is a nice piece.  No, not heavy.  It's just a nice cover for when you need a hint of warmth.
