Wardrobe choice is an important part of a successful Headshot and can give your shots that little bit of edge.
As a general rule darker colours and simple necklines are better and it is good to keep it as simple as possible. It is good however to consider a few different looks for more specific characters so have a think about how your likely to be cast and come prepared with appropriate options.
When using a colour headshot try wearing colours that work well with your skin tone and eye colour. You will be surprised how much difference certain colours will make your shots really stand out.
Lastly think about items of clothing that you love wearing and make you feel great and bring them to your headshot session. A favourite jacket, scarve, shirt or jumper etc will inject a bit of your own personal style into the shot and ensure your headshots show you looking and feeling great.
