This seems to have been their first interaction. Touching her was plainly a dumb-ass move. Plus his consistent deafness to her repeated "I'm not interested" feedback.
But his comment about professional dress could have been made far more constructively. When I encounter provocatively-dressed women in professional contexts, I'm immediately suspicious. Are they stylishly clueless? Are they trying to manipulate others? Are they making a point about women being free to dress as they like?
I mean, I invite you to log about outfits worn by your male and female professional colleagues. Assess overall tightness, especially legs, butt and breasts. Estimate percentage of bare skin, especially cleavage.
For example, you may see women in tight sleavless tshirts aka wifebeaters, plus short skirts. How many men will be wearing tight wifebeaters with short pants and sandals? Not many, I bet.
