Black striped dress with fabric stripes and sheer see-through stripes

I'm not sure if this is a dress or a cover-up or something newer over to bed but I like it it's really pretty and the purple you see on this is my mannequin it's purple so everything that you see is purple is because it's see through it says it's a size 2XL,I don't think it's right . The measurements from pit to pit is 20 from hip to hip is 18. the brand is auditions it's in perfect condition.T#2
