For your office holiday party, choose attire that balances festive cheer with workplace professionalism. Consider a semi-formal dress or skirt with a festive blouse, or a dressy top with tailored pants. If your office allows for more casual attire, opt for a stylish holiday sweater or top with dark-wash denim. Accessorize with jewelry, scarves, or a clutch bag that complements your outfit. Remember to keep the overall look sophisticated and appropriate for the occasion.
