The impression you make when presenting in front of an audience is driven by many different things, some obvious in terms of content, delivery, style and appearance.
There are also less obvious aspects that members of your audience consciously or unconsciously use to assess the quality of your presentation.
One of the (un)conscious aspects may be how you smell. It is never a good idea to have a very strong perfume. Maintain a neutral and professional fragrance.
Obviously you have brushed your teeth before, right?
