Do your homework: Your selection of the correct attire for a presentation will go a long way in making you feel at ease at the start of your presentation. But what is the correct attire? Try to establish ahead of time how the majority of your audience will be attired, and dress one step up, or at worst, the same. If you are dressed down from your audience you will lack credibility. Being dressed the same will create mutual comfort and is good for “information sharing” style presentations. One step up will give you added credibility and is therefore important if you’re trying to persuade.
