Shady Lady O/S waffle knit tunic/sweater dress

Never been worn grey waffle knit sweater dress. It is one size fits all, I suspect though it would fit fairly oversized on a small, and then more fitted on someone who normally wears a large. It is about 34” at the longest point, but it’s a very curved hem, so the sides go up higher. No tags on this (including no tags on size, brand or materials). Please ask any questions you have!
