Before going to your closet to select your "favorite" outfit, bear in mind that the video camera "sees" color, pattern and contrast differently than the human eye does. It's important to dress for the way the camera sees you. The most important rule to follow in selecting your on-camera outfit, is to keep it simple, plain and low-key. We want the audience to focus on you, your face and what you have to say, not what you are wearing.
Dress in clothes that you feel most comfortable in. We want the real you!
MEN: Should you desire to wear a tie, choose one that is non-shiny and compliments your suit, if planning to wear a jacket or vest. Formal dress is not expected in the interview, it's best if you dress in the manner you are most comfortable. If that's in a suit, go for it. If you're not a suit kind of guy, a casual button down shirt is great.
AVOID: "Loud" patterns, plaids, stripes or checks - the smaller the check, plaid or stripe, the worse it shows up on camera. These patterns create a distracting moire on-screen.
LIMIT: Glittery material, sequins or anything which is super shiny and reflects light.
MAKE-UP: If you wear make-up, apply as normal. If you tend to have a shinier complexion, please invest in some powder that closely matches your skin tone. Whereas glowing skin tends to reflect a youthful appearance in daily life, it just doesn't work that way on camera. You may not be accustomed to having powder on your face, but you'll be happy about this extra step once under the bright camera lights! I always bring a powder compact to the shoot day, just in case.
