Must a Second Wedding Be Different From a First Wedding?

While a second wedding shouldn't be a flashback or replica of a first wedding, it's absolutely fine to incorporate some of the same aspects, such as the members of the wedding party. If these people have remained near and dear to the bride, it doesn't matter that they were attendants in a previous wedding.

As for the bride’s attire, she's no longer restricted to items like pastel suits; she can don a beautiful white bridal gown -- do make sure it's age- and figure-appropriate, of course. It's also okay for the bride’s father to walk her down the aisle again and for the couple to register for gifts.

Also, with second weddings, you should find meaningful ways to include the couple’s children (if any) in the celebrations. This may be a difficult time for them, so it’s best to make every effort to keep them involved and comfortable.
