I will start by saying that this is NOT a dress. It is far too short to be a dress! It only just barely goes past my behind. However, that being said, it is perfect for my cosplay! Jedi tunics are usually around the same length, so it's good for that!
It is a turtleneck, but you cannot fold it, only scrunch it around your neck. Also, if you have an ample bosom, I would suggest wearing a belt with this tunic shirt, otherwise it may become a tent.
So, all in all, there are faults, but none of them really affect me since I'm only using it for a cosplay. For me, it's perfect!
