A "black-tie optional" dress code means tuxedos and floor-length gowns but guests have the flexibility to wear dark, formal suits and elegant cocktail dresses instead. It strikes a balance between traditional elegance and comfort, ensuring guests don't have to rent or buy ultra-formal attire.
For Men
You have two main paths. You can go all out with traditional black tie or choose standard formalwear.
Option 1 "Traditional": A black or midnight-blue tuxedo, a white dress shirt, black bow tie, a cummerbund or vest, and patent leather shoes.
Option 2 "Formal Suit": A dark-colored suit with a crisp white dress shirt, a conservative tie (solid or subtle pattern), and dress shoes.
For Women
You have the most flexibility, though floor-length styles are preferred since the hosts or bridal party will likely be wearing them.
Option 1 "Traditional": A floor-length evening gown made of elevated fabric like satin, silk, or chiffon.
Option 2 "Formal/Cocktail": A sophisticated, dressy cocktail dress (midi length) or an elegant pantsuit/jumpsuit. Avoid anything too casual, like sundresses or anything above the knee.
Quick Tips
Lean towards the formal side: Because the event is elevated, it is generally polite to dress up as much as you comfortably can.
Accessorize: Elevate a standard suit or a cocktail dress with elegant jewelry, formal heels, a sleek clutch, or a classic watch.

Note
If you'd like, you're welcome to dress according to the wedding color theme but this is in no way required. The theme colors besides white and black are buttercup yellow, tangerine orange, and basil green.
