Amazing vintage dress from Paris

I bought this dress in Paris at a vintage shop. It’s beautiful and perfect for an event or wedding. It has short slits at the front and a black slip dress underneath that’s a built in crop top and skirt. The back has a flattering keyhole opening. Back zipper closure. Fits tightly around the waist.
