Jordan Belfort makes an immediate positive impact on clients through his professional appearance and purposeful body language. He dresses smartly in dark, well-tailored suits and keeps well-groomed facial hair. Belfort uses exaggerated body language on calls to emphasize emotions and set the tone, and will increase these gestures as the sale progresses. However, appearing unprofessional through dirty or ill-fitting clothing as well as inappropriate body language can hinder sales success.
