Sometimes instead of a suit a white blouse with lace collar is worn with short pants. Contemporary Weddings Ring bearers at modern American weddings generally feature the ring bearer in Eton suit or junior tuxedo. Only the most formal wedding may have te ring bearer in Fauntleroy-style knickers or shorts. British weddings are somewhat more varied with a variety of costumes for the ring bearer from Fauntleroy styles to kilts and military uniforms. I have less information on other foreign styles.
Some images are available at actual weddings from various eras.
HBC has just begun to collect information on these weddings. In some cases only the image is available. In other instances some information is avaialble on the wedding. Often such small boys are selected to serve as ring bearers or pages that they do not complain about their costumes. Many are quite pleased to have an imortant role in such an important ceremony.
