P Petites ? Small ? vintage 60's ? 70's ? TRAVEL-LITE robe long nightgown dress

Pre-owned vintage nightgown and robe. Both have stains and flaws. The robe has the most stains and flaws to the material. The robe also has some missing stitching at the bottom hemline. The night gown has one flaw on the front and is stained around the armpits. See photos for the condition of both items. The tag says the size on both items is a "P" . I'm not sure if it stands for Petite but it appears to be equivalent to a size Small. Please check measurements below BEFORE purchasing these items to ensure a good fit. I'm also not sure of the decade of these items as it could possibly be from the 60's or 70's. Buyer is to view the photos and determine the decade for themselves.
