Best Woman or Man of Honor-What do they wear?

These customary roles are being reversed more and more lately. But what is the proper etiquette as far as what the Best Woman or Man of Honor should wear? According to Emily Post's Wedding Etiquette, the solution is quite simple. A male honor attendant should wear the same attire as the groom and groomsmen. A woman may wear a dress in the same color family as the bridesmaids', or she can choose a dress in black, gray or whatever the primary color worn by the groomsmen. Her attire should be within the formality of the wedding, but she wouldn't wear a tux or dress like the groomsmen. A man would wear a boutonniere, and woman would usually wear a corsage featuring the same flowers as in the groomsmen's boutonnieres.
