Married or not, the groom's honor attendant is called the best man. He host or organizes a bachelor party for the groom, help the groom dress for the wedding day, and signs the marriage license as an official witness. He also holds the officiant's fee until the groom needs it, and keeps the wedding ring until the groom needs it during the ceremony. The best man offers a toast to the couple at the reception, and he's the one responsible for arranging transportation or personally driving the bride and groom to their honeymoon hotel or to the airport. As a best man, surprise your groom with our fabulous gift ideas.
