CLEVELAND -- For many people, company holiday parties are quickly approaching.

To help you follow proper etiquette, here are a few tips.

Here's a list of business party etiquette from Hess and Lou Kennedy, nationally known authors on business etiquette. This is a list of no-nos:

• Mistake No. 1: The blow-off. The biggest error is not going to an office party that is a "must-attend" event.
• Mistake No. 2: Forgetting the boss is watching.
• Mistake No. 3: T-shirts and sandals. Inappropriate dress at an office party draws attention, but the wrong kind.

• Mistake No. 4: The Business-Talking Bore.
• Mistake No. 5: Me, Me, Me.
• Mistake No. 6: Who's the boss? Introduce yourself to senior managers.
• Mistake No. 7: Do not talk about pay.
• Mistake No. 8: Hanky-panky. No longer is an office party an excuse for employees to become intimate.
• Mistake No. 9: Office parties are extensions of the workplace and not campus free-for-alls.
• Mistake No. 10: Don't drink excessively.

Oh, What To Wear?

According to Hilka Klinkenberg, founder of Etiquette International, a firm specializing in business etiquette, be sure dress appropriately for the occasion.

Klinkenberg said this rule especially applies to women who sometimes use company parties for strutting their stuff.

Anything short, tight or revealing should stay in the closet. You've worked hard to create a professional image, and revealing clothes can alter your coworkers' and boss's perception of you as a competent professional.
