Another thing to consider when selecting what to wear is the location of the final portrait. If it will hang in the living room over the fireplace, you should try to incorporate the color scheme of the room into your clothing choices.
Of course you will want to choose outfits that fit your personality and make you feel more attractive. You don’t want to color coordinate with the fireplace if the outfit is going to make you feel creepy.
Create color harmony and ensure that all outfits are coordinated. Avoid patterns or stripes — solid, neutral color look the best. Avoid wearing short skirts or shorts, as they make posing more difficult. Long, flowing dresses, jeans, and khakis make better selections.
Sleeveless shirts or tops with very short sleeves are sometimes very unflattering in portraits, thus should be avoided.
Because shoes often show in portraits, ensure that the shoes you wear compliment your clothing. However, bare feet also works in many cases.
