The differences between leadership styles are not necessarily positive or negative in building leadership, but executives need to be aware of their style and how they come across to others in their organization and outside.
A year ago I went to a wedding where the bridesmaids wore identical dresses and the maid of honor wore a dress that was longer and a different style and color. For that wedding, the bride only chose the dresses for her bridesmaids and allowed the maid of honor to pick out her own dress.
The maid/matron of honor is part worker bee, part emotional lifeboat. Chosen for your energetic, get-the-ball-in-motion qualities, you should also remember that listening to the bride, making her laugh, and offering emotional and logistical support are also part of your honor attendant package.
