Even in workplaces where casual dress is the norm, managers and leaders wonder whether they should be dressing differently—that is, better—than their team members. Here are some points to consider:
Dress to express, not to impress. That is, your clothes should reflect your attitudes toward work, not your status as a manager with power over others. Dress well enough to show that you take your job seriously, but don't wear clothes you don't like simply because they make you look like an authority figure.
Dress to set an example. Your younger workers especially may have only a vague idea of what "proper business attire" is, so they'll take their cues from you, and they're unlikely to dress better than you.
