Whether you’re the newbie in the workplace or a veteran, the office holiday party is usually one of the most anticipated workdays of the year. You’ve worked hard day in and day out to meet what may be sometimes be aggressive goals. Now is the one time of year that you get to be in the same room as all of your coworkers celebrating the company’s successes and letting your hair down. Though letting your hair down is perfectly acceptable for any office holiday party, you do need to keep it slightly professional. This goes for your choice of outfit and makeup as well.
