Always wear clothes that match your style and personality. Color is great for tops, but keep in mind that bright colors tend to draw attention away from your face, so consider choosing something neutral that complements your eye color and skin tone. Be sure that your clothes are clean and neatly pressed. This is especially true for collared shirts and suits. Have them looking sharp, as the camera picks up a lot of detail. If you are doing a headshot, your lower half won't make it into the final pictures. But don't neglect wearing pants or a skirt that will make you feel confident for your appointment. Make sure to dress comfortably, but in attire that is appropriate for your line of work. Confidence and comfort help you achieve your best image. Stay away from clothes are are too tight or uncomfortable. Don't underestimate being well-rested, and be sure to drink plenty of water in the days before your shoot.
