Varying Arm Exposure
As you become more familiar in the workplace, express more personal taste with styles that convey a similar level of credibility. Dark colors with high contrast near the face communicate the most powerful version. Styles that cover the arms, or at least the shoulders, and keep neckline modest support credibility and show respect for the workplace. Menswear does not allow short sleeves so this is one gender difference. Perhaps less arm exposure is more credible for women as well? Quality fit avoids calling attention to the body. Shoes that relate to overall garment color help keep focus on the face. Open toed shoes are usually inappropriate so clarify in advance of wearing them.
