Plain colours are your best choice. Patterns or prints distract and date your photo. Choose mid- tone colours in blue, green, wine and purple because they are universally flattering. Avoid wearing tops in flesh tones (cream, beige, pastels, peach or yellow) as they will blend your face into your clothes.
