How we change what others think, feel, believe and do
When doing a presentation or making a speech, it is more than the words that is important in persuading your audience.
Make sure you are scrupulously clean. Shower. Trim and scrub your nails. Take a haircut. Brush and set it well. If you have facial hair, trim it neatly. Shave well.
A simple rule is 'Dress to impress', which means what you should wear can can vary greatly with your audience.

The reason to wear a dark suit is that black is a receding color and is noticed less. A white or pale shirt forms a triangle with your face, where you want your audience to attend.
Power dressing is appropriate when power will impress, such as in a high-level business setting. It is a particularly male thing to play games of status and they will likely pay attention more to someone they see as superior and ignore those who seem inferior.
