black long sleeve dress with open back Kiah Backless Maxi in have piece from Fashionkilla. Long Sleeve Backless Buckle Maxi

There are elasticated keeper tabs at the top of the zipper and a protective keeper with spur rest at the heel

I wore a very similar style (in white) for my bridal shower last year and its one of my favorite Spring dresses

Like Sylvia's outfit above, this is still amazingly classic, and in the right circumstances could be worn today
