Gray tunic 90s vintage

Originally part of a pant suit, this top is vintage 90s Sans Tambours Ni Trompettes - made in France. Rayon/spandex blend. Slightly sheer with covered buttons and a sleek line. Length approximately 36” from back collar, pit to pit 19”. See photos for any flaws. I do have the trousers but they’d need a new elastic waistband.
