Before you get started. Keep in mid this will be a video you are creating to promote yourself as well as your product. Some products can promote themselves visually by the just simply looking good. This will make things a little easier for your.
But how should you dress?
Wearing the right clothing could make or break your video. Wearing a suit and tie is not necessary. We want the audience to connect with us as a real person. Projecting the image of a real person helps people understand that you are speaking at their level. Unless you are promoting a law firm that works in hi end cases with million dollar payout, this may not be your image.
We want to be presentable but not looking like we are related to PigPen. Casual dress that will be neat and clean. You can also keep in mind how much of you the camera will be seeing. If you are only seeing from your midline up, who cares what type of pants you are wearing.
