Vintage one piece with attached vest

Vintage one piece jumpsuit with attached vest that buttons in front and has a tie in the back. Had zipper in the back as well. The colour is a muted blue- slate. The vest has floral detailing. A previous owner had hemmed the pants, so fits best on a shorter person (I’m 5-3 for reference). Im assuming the fit would be a medium as I generally wear a small and it’s a little loose - but there’s no tag to be certain. Comes from home with cat.
