It is appropriate to wear black to an afternoon wedding. Black is no longer just associated with mourning. It has become a classic color, fashionable for almost any occasion.
Since a wedding is a celebration, a black outfit should appear festive rather than dour with the cut and material appropriate for the setting. Black is also versatile. Depending upon the formality of the occasion, accessories, such as jewelry and shoes, dress up or dress down the outfit. For an afternoon wedding, a long gold chain or strands of colored gemstones add a joyful touch. The main thing to remember is to avoid wearing an ensemble that detracts attention from the bride.
