Research consistently shows:

Your clothing has a big influence on people’s perceptions of you

Women who wear sexy clothing receive lower competency and performance ratings; are paid less and are less likely to be promoted.

Why does it matter...?
When you call attention to your sexuality or femininity, it also calls attention to feminine traits (such as emotional, sensual, vulnerable) rather than traits considered essential for management success (like decisiveness, confidence, authority), resulting in lower performance ratings and fewer promotions and raises.
Consider your past performance ratings and promotions; any chance you may have been held back by your workplace dress?

What is one change you could make in your workplace dress to enhance your probability of success?
