Semi-formal dress code is a dressier outfit than what you would wear to an office but not as dressy as a formal evening gown or tuxedo. It is typically worn to weddings, holiday parties, fine restaurants, and some teen and preteen dances. If the event is held in the evening, the semi-formal guidelines lean more toward the formal than if it were held during the day. The semi-formal dress code is also referred to as "Half Dress" because in Latin, "semi" means half. It falls just below Black Tie Optional and above Cocktail Attire on the formality scale. The dress code is slightly more relaxed than formal attire but still requires a blazer with matching dress pants or a 2-piece suit, along with a dress shirt and in most cases, a tie. Some options for semi-formal attire include dresses, separates, or a suit in a dressy fabric, such as silk, cashmere, or satin. For men, it is recommended to dress on the more formal side while taking into consideration what the event is for. Solid, darker colors and subtle patterns, such as a classic floral print or stripe, are always safe bets for this dress code. It is important to clarify specifically what is meant by semi-formal if you are not sure, and there is nothing wrong with contacting the host to ask for more specific information.
