We would like for everyone to dress in semi formal attire. Examples: Gentlemen: A well-fitted suit in a classic color like navy, charcoal, or black. Khakis or slacks with a crisp button down shirt (tie and sport coat are optional) Ladies: Dresses with shorter hemlines, such as knee-length or midi-length dresses. A pantsuit, cocktail dress, or a dress with a tea-length skirt.
