Black Maxi Dress/Skirt

It’s super stretchy and can be worn either as a dress or skirt( I couldn’t get a picture of it as a skirt because I’m 5’1 and it’s really long on me and I couldn’t get a good shot of it). I bought it new but had to roll it a whole bunch so I cut the tag so it wouldn’t show in the roll. I don’t know what brand or size it is but I’m guessing it could be a medium. I got it from Macy’s.
