A tiara conjures up the diamond-studded grandeur of a royal court. If your hair is fine or straight, go for a light metallic bandeau or one made of flexible wire. It should be secure and comfortable as you walk down the aisle and dance with your groom. Sparkling barrettes, hairpins, and combs also make beautiful accessories for brides and attendants, as do fresh silk flowers, which can create an effect that’s subtle or striking.
