As a personal stylist, I work with many successful professional business women. It has been my experience that my clients dress to impress their clients. It completely makes sense.
I infrequently encounter people who don't take the concept of dressing for success seriously. To validate that our attire matters, I scoured the internet for scientific evidence that confirmed what you wear impacts your results. And whether you like it or not, what you wear influences other's perceptions but can also influence your own performance. I discuss my findings in this video.
