When choosing your clothing for you professional headshots avoid complex patterns like stripes or checks and opt for solid colors wherever possible. This will not only give the headshot a more classic look but will be more tolerable to look at in several years when styles and trends have changed. Horizontal lines can be difficult to look at. Varying patterns on different articles of clothing can make for a disaster of a headshot. Vertical lines in clothes should be minimal but the presence of them can have a slimming effect.
For men, it is often a no-brainer. A business suit is a good choice for a corporate head shot. If you want a more casual look, you can forgo the blazer and wear a white shirt with a tie. For blazers, grey or navies in solid colors are often a good choice for timeless portraits. You do nott want clothing or hairstyles to look too trendy as it can date the photograph and many companies will expect the corporate headshot to last a long time for the investment they are about to make.
Wardrobe choices for corporate headshots can feel more complicated for women but choosing a classic business suit or simple blouse and skirt or pants is a great idea. Again, do not wear anything too trendy and choose something that is for fall or winter instead of summery for your headshot photography session.
