The Dress Code for our Wedding is Semi-Formal or Cocktail Attire. This means our Wedding is less formal than black tie, which means no tux required for men and no floor-length gown required for women (unless you'd like to wear a long dress). Examples for Him: A suit and tie or a dress shirt and slacks. Examples for Her: A cocktail dress or dressy suit or jumpsuit. Rompers and separates are also viable semi-formal wedding attire options. Our Ceremony will be held outdoors and will be on grass, so you may want to consider wearing flats or wedges to avoid having your heels sink into the grass.
