Tunic not dress
This is absolutely beautiful.  but i am only 5'6"and the dress hits my thigh about the same place as it does on the model. one lean over to pick up my purse off the floor and i will flash everyone.   so i am going to wear it with dark denim leggings and tall boots.   likewise i did not detect even a speck of black. to me it is navy and purple. i was wishing it had black because those are my favorite leggings but quite honestly i think you're going to have to do navy or denim.
