It's kind of gothic like, though I'm not a goth myself, but I thought this dress was beautiful. I would just wear it like this with nothing else (except some black high heels). Do you think it is nice, or maybe to goth?
I think you might inadvertently dishonor your grandparents with that dress. I suggest going with something pretty conservative. It can be a little sexy but nothing overt. Stiletto pumps dress up any dress and make you into a vision.
It's kinda a Halloween party type of dress. Definitely not to something for a 50 year anniversary. Maybe if it was even all the way around the bottom but still then it would be more of a cocktail dress. Good luck with your search!
It is lovely but perhaps a little too racy for your grandparent's wedding anniversary? I would suggest something a little more covered up (not nun-like but just less cleavage and thigh) for this particular occasion.
