Vintage 70s Striped Knit Top

True vintage 1970's striped knit tunic-style top. Keyhole neckline with a thread loop & button closure. 3/4 kimono sleeves. The label is shredded and I don't recognize the maker. If anyone does, please comment or message me! No material tag but definitely feels like polyester. No size tag either, but estimating a M. Color is more coral than is reading in the photos. Added a photo next to a red sweater, to show the difference. The button is coral and is not the same shade as the material. Fabric does have some give, but not a lot. Approximate measurements, taken on the outside of the garment laid flat, unless specified are - Pit to Pit: 18.5" Shoulder: 17.75" seam to seam Length: 24.5" Sleeve: 14.5" Flaws: A couple of snags on one spot of the front (like a bracelet snagged it). If the label weren't so destroyed I would think this had been barely worn!
