There seems to be a growing debate as to whether or not presentation dress code is becoming less formal or not. This could depend on where you are presenting (country, place), and who you’re presenting to (audience). Faced with this question, a little research can solve the dillema for you quite easily. First, find out how your audience is likely to be dressed for your presentation. The rule is: You should dress either similarly, or one step up from your audience. If you are at all uncertain, then dress “up”. If the audience is familiar and/or friendly, dressing similarly is acceptable. If the gap is too severe, your audience may feel intimidated and may not warm to you.
