What do we think of wearing an unzipped dress and this V-shaped open back?

I’ve unzipped my dress and now I am obsessed with this type of open back. Ive done a search and most open back clothes have pretty skanky ur unflattering cuts in the back (Ive been looking at affordable stores). Is there a name for this shape, how do I search for it? Have you ever tried just wearing an unzipped dress? 😅
