Wear simple and basic clothing with solid colors, avoiding loud, busy, or new trendy patterns, as well as name brand logos. Many people opt for blues and medium tone grays.
Avoid fluorescent/neon colors because they reproduce poorly and detract from the face.
Please do not wear white shirts when photographed with standard white backgrounds. It’s smart to dress conservatively for required government photographs.
Take heed to avoid getting sunburned before your photo session.
Get your hair done if you like, but nothing flamboyant. You may wear long hair down, but it must not cover the face.
Make-up: Keep it minimal and matte toned. Avoid shiny lip gloss.
Please do not apply shiny facial moisturizer.
Avoid big hanging earrings, and chunky or shiny/sparkly jewelry.
Aim for looking like you’re ready for a job interview, not a party.
Finally, neutral and pleasant expressions are better than “not smiling”.
