>Why not? If a man (fellow coworker) has nice biceps, I say it (I'm not gay, not trying to seduce him, but being fit is very high on my values list). If a woman (fellow coworker) is cute, I say it (I'm not trying to seduce her, I just think it's nice to give compliments).

What about if a man has a nice bulge in his pants? Will you compliment him on that too? Because a reference to a low cut top is a reference to what lies under the top, and I'm not talking biceps. The male equivalent would be a not so subtle compliment on his penis.
