Black Tie Optional can be one of the most bewildering invitations for a guest to receive. But the good news is that it's not that hard and it gives you a range of options (meaning you might just be able to wear something out of your own closet!)
All that "Black Tie Optional" means is that you have the option of wearing anything from a cocktail dress to a formal gown. I've chosen this rose satin dress as an example because while it is cocktail length, the beading and fabrics make it fancier.
