Vintage-late80’s-early90’s Jacket/tank, size M?

Very “budding female manager in the eighties” power combo, but also really cute with a pair of leggings today. Back of tank is the same grey crepe-like material of the jacket. Both are also cute separate. No stains or noticeable damage Tags are unreadable. Based on who wore it I’m going to guess M. 40% off all bundles!
