For the Ladies
Ladies should wear a cocktail dress, casual maxi dress, or a dressy skirt and top. An elegant pantsuit, or jumpsuit would also work well. Consider the low country heat and dress accordingly. 
Note: Guests will be walking across the grass lawn throughout the ceremony and reception. Opt for comfortable footwear such as a thick heel, wedges, or formal flats.
For the Men
Men should wear slacks or dress pants paired with a dress shirt that is suitable for warm weather. Sport coat and tie are optional.
