I would suggest natural and earthy tones like beige, cream, tan, brown, white, gray, olive, rust, muted blues, and occasionally black. These colors will compliment your skin tone to keep the focus on YOU, rather than your clothing. It will also compliment outdoor and indoor settings. Please avoid bright or neon colors especially red, orange, and pink. Flowy clothing is always preferred, if possible, because it shows movement and photographs really nicely.
