For a television interview you should aim to wear something you feel comfortable in – this will help you give a calm and confident performance.   However you want to look smart as well. If you are constantly worrying that you ‘don’t look right’ you are likely to feel distracted by this, and come over as uncomfortable. Wear a plain shirt or blouse if possible; nothing that will distract viewers from what you are saying. This means avoiding bright colours and severe patterns. It is useful to wear a jacket as it will be easier for the production team to attach the lapel microphone while hiding the cable. These microphones are extremely sensitive so avoid wearing clunky jewellery that will create noise when you move, and may become a visual distraction for the viewer. The audience should be focused on what you’re saying, not mesmerised by aspects of your appearance.
