Romantic, a little edgy lace trim cardigan/coverup, M/L

Possibly vintage stretchy black (not sweater) cardigan/coverup with lovely layer of lace around neckline and hem. Instructions are faded, tag says XL but runs small, M/L imo. Mannequin is size 6 for reference. A rogue fuzzy in the lace (indicative of material and age) but no pilling, holes etc. Still very soft. 1 hook/eye closure in front and *subtle iron mark? On back of sleeve, noted.
