Philadelphia Headshot Photography Style and Fashion Guide by Laura Eaton of PhiladelphiaHeadshot.com
The question I get before nearly every headshot session is “what should I wear?” My answer is always wear what you feel best in, and to bring more than you think you will need. It is better to have too many choices than not enough. There are no “rules,” but I do recommend avoiding logos and overly busy patterns. I also recommend bringing a variety of looks, so you can have some images that are more formal (for LinkedIn and your website) and some more casual (for your personal Facebook page, or dating websites). 
If you are a creative professionals or work in a more casual environment, jeans are a totally acceptable option. Good fit is essential and go for a more tailored look than your “weekend” jeans. You can express your style with jewelry, such as a statement necklace, or go simple with something more delicate. Layers, like a cardigan or jacket can add visual interest and allows you to accomplish two different looks without a complete wardrobe change.
If you work in a corporate environment, or serve corporate clients, conservative looks are usually your best bet. But corporate looks don’t have to be boring, or just in a black or grey palette. A pop of color can brighten up your face and make your image stand out. Our eyes naturally gravitate to color.
If you are a free spirit and your job allows you to pursue your passions, you can let your clothing communicate your personality.
If you are an actress, casting directors are generally looking for clean & simple headshot, they want to see your personality shining through the image, and not be distracted by large jewelry or too much color. A black palette keeps the focus on your face.
