I got this comic print dress from Torrid. This is a size 4 on me after I shorted the straps. In my opinion is runs a little large and the fabric is a super stretchy polyester/spandex knit (sort of like bathing suit material).
The scoop neckline is cut a bit low and the arm holes are also a bit large. It's super comfortable. I'm also wearing instant sleeves from Lucie Lu.
