Want a break from all the messy news about Donald Trump Jr. and Russiagate? Let's cut to some other topics that are roiling America: Is it acceptable for women to go sleeveless and bare their toes in a professional setting? And what about cleavage in the workplace?

Before I get to cleavage (don't worry, I will cover it), can we at least agree that a female lawyer baring her arms is no longer scandalous?

Indeed, at some firms, the tailored sleeveless dress seems to be a summer uniform, like the women at Debevoise & Plimpton. Several weeks ago, I attended the firm's annual women's cocktail party at Rockefeller Center and it seemed like every other women there had on a jaunty sheath dress. (And may I just say that they looked fetching and toned—just as they did at last year's party?)
