SHIRT ON. Shirtless is classless. I hear the excuse that it's too warm when they're working outdoors. I care not. Women work outdoors and we don't have the luxury of removing our tops. Also, when I was giving online dating a try, I can't tell you how many men posed for pix w/their shirts off and 99% of them really needed to keep them on. Even if a guy has the body, he should save the viewing for his SO when they're alone. To me, it's the height of arrogance to walk around shirtless. I repeat, shirtless is classless.
