Favorite Vintage Dress

I have a favorite of my vintage dresses and of course it is black. This dress once belonged to my best friend about 18 years ago. This dress is perfect. It has a pencil skirt and tank straps, zips up the back and has a small bow on the bodice. The dress is probably from the sixties, but it is hard to tell. The fabric is old and the seams are now weak. I hope it lasts for a few more years.
