TGIF! This piece from WhoWhatWear is a good reminder.
While appearance may not be our #1 priority in our personal lives, looking older* can be a problem in the workplace, leading us to be unfairly marginalized. Your bosses and colleagues might not even know why they think you aren’t “current”, but what you wear influences their perceptions on a deep subliminal level.
*NOTE: Being perceived as too young can also hurt your career. Dress professionally, and leave the sneakers, baseball shirts etc. at home.
