The title alone may sound boring but professional attire does not have to be! Professional attire and/or that job interview outfit may vary depending on what industry you are in, but if you are like me, working in a professional environment, conservative is key. Again, conservative doesn't have to be boring, instead it can be classy and timeless.
And also, don't forget to smile! Smiling is contagious and sometimes even if the day is stressful a smile from a coworker makes me feel better!
