Jeffrey & Dora vintage 1980s work where modest pants suit women’s small Black

This outfit is in great used condition, the only flaw to note is that I do not see a size tag, material, tag, and one of the shoulder pads is coming loose. Otherwise this piece is in great shape. It is a one piece that looks like a two piece. The front has a zipper hidden behind The button closure. This tag I am able to find says it is a petite, so I am going to assume it is size small
