What to wear to your photoshoot?
Short answer, whatever you would normally. I do not worry too much about what my clients wear, because I want to capture you as you usually are. Wear the outfit that you want to reflect in the photoshoot as a whole.
Are these photos for your LinkedIn profile? Wear business attire. Family photos for this year's Holiday cards? Wear more dressed up winter-wear. For everything else, choose outfits that are casual, clothes that are in good condition, and have an overall color scheme that fits the location.
