In town, one should be dressed properly. Outside of a lido there is no excuse for acres of flesh. Specifically I am thinking of the dismal British trope of a bare-chested man sauntering along the high street. Men, to be clear: no one wants to see your sweaty, shirtless body. Especially on public transport. Nipples for all genders should be kept firmly under wraps. If you are wearing a shirt (appreciate you) then keep an eye on chest unveiling. Unless yours is a perfectly buffed, well-kempt example, unbutton with caution. Too much heavage/cleavage or unleashed chest hair is unwarranted. Excessive flesh in an office is uncouth and uncomfortable for all, especially, I imagine, the chick riffling around in micro shorts on an itchy swivel chair.
