This set includes a fitted sheet, flat sheet and pillowcase from JCPenney. The sheets are marked twin and the pillowcases marked standard. The flat sheet is seemingly oversized for the twin bed. Then the duvet cover is on the small side. You can see the measurements in the pictures (approximately 50 x 71 inches) it has ties for closure. It does not have a tag inside. I don't know that it's from JCPenney but it was with these sheets at the estate sale. And in my opinion the colors seem to match. All in vintage condition. Overall there's a little bit of fading. There's a couple of small light colored discolorations on the pillowcase. And the duvet cover has a small amount of pilling, but I don't see any stains. No holes or rips. It's from a smoke free stain and I don't detect any musty odors (but of course this can be subjective).
