Vintage knit made in Canada button up vest size large (fits like a small)

In great pre-loved vintage condition. This made in Canada vintage vest is knit in a beautiful pattern with ribbed hem. Four button closure v-neck. I am not exactly sure how to describe the colour. The second photo is the best representation of colour (maybe a dark salmon?). 100% Acrylic. No rips, tears, holes or stains. Size is vintage large which I would say would be today's small/medium. Please review measurements below to ensure a proper fit. Laid flat measurements: Pit to pit: 17.5" Center back length from base of collar to bottom hem: 20" Waist opening seam to seam in relaxed state: 14"
