Formal style is important in professional contexts to convey respect and professionalism.
Formal style of writing is typically used in professional contexts where respect and professionalism are crucial. One would most likely use a formal style when presenting a member of the military with a medal of honor, in order to uphold the solemnity and significance of the event.
