Whatever your goals might be, your photographer will help direct you so that your images will convey confidence, competence, approachability, and trustworthiness. A good rule of thumb is to wear what you might wear to a business meeting, or what you would wear to an interview. The goal is to strike a balance between uniqueness and uniformity. A helpful resource for wardrobe inspiration is to look at other Linkedin profiles in your industry and find 2 or 3 options for outfits that match what’s in your wardrobe.
Choose something that is flattering and fits your body type. A jacket that is too large or a shirt that is too small can be distracting. Make sure that everything is wrinkle-free and clean. And if you are unsure about what you should wear, bring options and your photographer will help you decide.
