A tailored suit, an evening dress or a wedding gown are all appropriate attire. Wedding consultants and etiquette experts advise the second-time bride against wearing pure white unless her first marriage was short, or she eloped. Brides who choose white for their second marriages tend to make their choice a less formal, less traditional gown. Most second-time brides are uncomfortable about wearing pure white. If that's how you feel, a shade of off-white or almost any flattering color is fine.
Many brides opt to choose a dress which they can wear again after the wedding.
A suit or cocktail dress are most appropriate, but pretty much all the borders can be stretched, except . . . Keep in mind that this is a joyful celebration of new beginnings. Keep in mind that this is an occasion to celebrate with your friends and family. Keep in mind the delicate balance of old and new relationships and levels of comfort and sensitivity. Planning your second wedding with an open mind and an open heart will result in an event that creates special memories for everyone participates in it with you.
