Black sundress

This is a black sundress with smocked top. I cut the label out of it because it itched, but the size label is still there. It says Medium, but I think it would fit someone much larger than medium. Length from top of shoulder to the bottom is 47-48" and from under arm to under arm is about 20". It would stretch to more than that. It's either rayon or a very soft cotton. I washed it recently and hung it up to dry, and it didn't need ironing. It only needs an iron if it hangs in the closet too long and the bottom part holds the wavy wrinkles. It was $100, but with no label, I'm offering it for a fraction of that.
