You will look most natural when you are comfortable. Here are some general clothing/make-up suggestions:
1) Extra mascara/eye shadow helps to bring out the eyes.
2) I retouch minor blemishes for no extra charge.
3) Wear warm colors( red, brown, orange, gold, dark green) in fall and cool colors in spring/summer (beige, pink, light blue, pale green etc.) . Avoid white if possible.
4) Don't try new hairstyles right before your photo session.
5) You may want to avoid very short skirts, as they will restrict your movements.
6) Baggy clothing may make you appear larger than you are.
7) Avoid clothes with words, except school logo. Be mindful of clothing with print, it may shift focus off your face.
8) It is best to wear long sleeves. They eye is drawn to skin. The focus of the picture should be your face.
9)Tan lines are seen on pictures and are hard to retouch.
10 ) Manicure and pedicure are suggested.
