The suggested dress code for the wedding and reception is semi-formal For Women: A knee-length or midi-length dress is a classic choice. A formal gown is too much, but a casual sundress is too little. A chic jumpsuit or a dressy pantsuit is a stylish alternative to a dress. For Men: A Suit with a tie is ideal. Consider a blazer with dress pants and a collared shirt if a full suit isn't preferred. Things to Avoid: Jeans, t-shirts, sneakers, and overly casual attire.
