80s linen blend Liz Claiborne boxy short knit sleeveless top sz M made in Korea

Likely from the 80s era. Good vintage condition with no rips, holes or stains. This is a boxy knit shirt made of 55% linen and 45% cotton. The last photo is the closest depiction of colour. Would look great paired with some wide leg pants. Tag says size is M; however, please review measurements below to ensure a proper fit. Vintage items tend to run a bit smaller. Approximate laid flat measurements: Pit to pit: 20" Arm hole opening: 6.5" Center back length from top of collar to bottom hem: 17"
