What to Wear
The clothing you choose is a very important part of planning your session. Find several different looks. Try to find one dressy, one casual and a few things in between. Accessories look great in photos. Bring hats, scarves, boots, etc. If you play a sport, bring the entire setup, uniforms and all. If you play an instrument, feel free to bring it to add to the photos. Tan lines and chipped nail polish WILL show up in portraits. If you are normally clean shaven, shave about an hour before your session. Solids generally photograph better than bright patterns; light colors (especially white), tight fitting tops, and horizontal lines tend to accent weight. Dark colors (especially black), loose fitting tops, and vertical lines have a slimming effect. Avoid drastically changing your hairstyle or color right before your session.
