Many people have been asking about the Beach Chic dress code. Beach Chic is similar to Resort Attire, attire that is appropriate for dinner at an up-scale resort or cruise. Also, beach weddings do allow for more relaxed attire than more traditional weddings.
Since it will probably be very hot and somewhat humid, please wear lightweight clothing, and since the reception will be on the beach, please choose your footwear accordingly. We want everyone to be comfortable and to enjoy the festivities.
For the ladies, flowing airy summer evening dresses or formal sundresses will work. In addition, it wouldn’t hurt to bring a lightweight shawl, just in case it gets cool.
Men can opt for lightweight pants such as khaki’s or linen, or a summer suit (no jacket or tie required). Lightweight button down shirts, short or long sleeves, are perfectly acceptable. If you want to change into shorts for the reception, your hotel room will be close by, so feel free to go ahead and do so. In this case, dressy shorts would be appropriate.
