What is the Wedding Guest Dress Code?
**Semi-Formal Attire**
Women: Women can choose to dress in a maxi or midi length dress, or other jumpsuit/pantsuit options! Spring colors suggested.
Men: Men can wear a nice dress shirt and an optional tie with dress slacks. If you choose, suit jackets are optional since this is an evening wedding. The groomsmen will be in dusty grey suits and the groom is wearing a navy blue suit, so please deter from wearing these colors.
