Zara tunic shirt

This is a size medium black tunic shirt made by Zara. It is NWT. It has split sides at the bottom and long sleeves that close with a button. There is a hidden button in the neckline that will open it up a bit more. There was weird light coming through my window and it makes it look like there’s some discoloration in the front and back but there is not. It’s in perfect condition.
