General Advice

• What you wear to the beach will depend on the climate and weather the day of the wedding. If the day is going to be windy or cold, wear wool and other warming materials, plus a sweater if you think you'll get cold. For the summertime, wear lightweight materials such as cotton and linen. If the wedding will be situated on the sand, wear sandals instead of formal shoes.
  
  

For Women

• Just because the wedding will take place on the beach does not mean you should show up to the ceremony wearing a tube top and shorts. You still have to look elegant, even if you will not be wearing a formal gown. Remember also that today is the bride's special day; one for which she has planned for months. Let her bask in the spotlight. Refrain from wearing white or off-white colors and avoid anything too skin-bearing, such as tops that show off too much cleavage or very short skirts.
  
  For the wedding, wear a simple floral summer dress or an outfit with a bold tropical color to match the beach setting, such as a bright blue or orange. Because beach weddings are more relaxed affairs than those that take place indoors, you can leave your expensive jewelry behind.
  
  

For Men

• A wedding on a beach does not require you to wear an expensive black tuxedo and tie, but try to keep some semblance of class in your attire. Refrain from wearing a straw hat, for instance, and other beach-appropriate but not wedding-appropriate items.
  
  Think about wearing a nice pale-colored suit made out of cotton, or a polo shirt with tan slacks. Because the wedding is on a beach, you are given the option of wearing more casual clothing, so opt for something you might wear to a family reunion, for example. Consult the wedding party if you cannot come up with anything you think would be appropriate.
