Robell Vintage Black Strapless Lace Dress

I bought this dress in a London vintage shop in 1989! It’s traveled with me, but alas I’ve accepted I will not wear it again. At the time they told me it was an early 1960s dress, but I have no way of knowing. It’s clean and in good shape as far as I see. The only thing is that the clasp at the top of the zipper needs repair (see images). Having said that, I’ve included as many pictures as possible and am selling AS-IS. It’s a strapless black dress with intricate lace, and a taffeta-type material. Perfect for elegant events.
