The color black has long been associated with mourning and death in many cultures. In the past, wearing black clothing to a funeral was regarded as the only appropriate choice. Many people still choose to follow tradition and only wear black clothing to funerals. However, today's society has seen a relaxing of the “rules" so that other clothing is now considered appropriate, as long as it is conservative in style and color.
For both men and women, a good general guideline is to wear clothing that would be suitable for attending a business meeting or job interview.
For women, a conservatively cut dress, a skirt suit or a pant suit, a blouse (with sleeves) or a sweater combined with a skirt of conservative length are all appropriate choices. Flat shoes or pumps in conservative colors may complete the outfit.
For men, appropriate clothing choices include a suit with a tie; pants and a collared, button-down shirt with a tie and a belt; and dress shoes or loafers.
