Your clothes should reflect the expectations of your industry, while also bringing out your personality. It’s good to stay within a range of expectations for your field, but it’s really good to stand out and get noticed. So it’s important to express yourself through clothing, posing, and facial expression. If you are in a conservative industry like banking, then professional clothes are important. You will want to use your body language to show your unique appeal. If you are in a creative industry like architecture or graphic design, then you have room to express your style and personality through your clothing. Your professional goals will help dictate what choices to make for your clothes. As a general rule, solid colors look good in portraits, and form-fitting clothes with sleeves help you look slim. When you’re unsure, these are good rules to follow.
