Black Tie Optional-more formal than cocktail attire, slightly less strict than full black tie. For Men: A tuxedo is encouraged but not required, a dark, formal suit with a tie is completely acceptable! For women: a floor length gown is appropriate but not mandatory. A formal cocktail dress or a formal jumpsuit also works! Link to Pinterest board for outfit inspiration: https://www.pinterest.com/mariahmoses18/wedding-guest-outfit-inspiration/
