This is labeled as sleepwear.

It’s just the top, but it’s very thin and tissuey .

21 inches from armpit to armpit even though it’s a Small. In other words, it would fit comfortably.

It has a rolled hem, and raw cut sleeves. Please see the photos. I believe it came like this and that this is not a modification.

There is a rectangular light spot on the back which I believe came from ironing this top.

That’s my hunch, but the fact that it is a comfortable sleep T-shirt, and a rather heathered black gray it doesn’t bother me, but feel it needs pointed out.
