Think about what you’re wearing, and how you’re looking. How would you dress if this were a presentation to “real” people? Treat this the same – brush your hair, do your make-up (yes guys, a bit of powder does no harm, especially if like me you have a shiny head)
Try and avoid clothes that have intricate patterns, these can look odd on camera and be distracting, but a bit of colour is great.
Also avoid noisy clothes – cotton and wool are good, but fabrics like man made fibres can disrupt the sound when you move about.
Think about how you are sitting – avoid slouching – upright and straight works best and will make you look more engaged. Don’t forget to smile!
