Wedding Dress Codes- Black Tie Optional Black Tie Optional: Women, you’re safe wearing just a short dress here. Keep it classy with some heels and a bold clutch. Men, feel free to wear a dark suit! While you probably won’t see many men wearing tuxes, if you’re feeling fancy-schmancy, go for it. But I warn you, if the invite says ‘black tie optional’ you may be the only one wearing a tux.
Certain parties, a wedding or social gathering, often send invitations that says, "black tie optional" on the invitations. There are many fabulous options of attire for both men and women to choose from for this occasion.
