Apt 9 black heathered tunic top/dress small

Brand new black heathered dress. Does have stretch to it and can be worn as a short dress or a long tunic top I’m not sure which it is supposed to be. I would personally wear as a top because of the length but I prefer a longer length in dresses and it could be easily worn as either. Great alone or with a pair of leggings. It is a size small
