the sensitive part of the male body is not on the top of his body like that of the the female that contains the breast which somany people consider a private part. In most setting, as a man, you could afford to walk round the street in bare chest with mere nickers and no one would make a big deal of it but when it's unlike exposing your breast just because you're trying to prove the gender equality concept right.

Everyone has the right to wear whatever dress he chooses to put on but a mother ought to at least respect her husband enough not to dress inappropriately in public. The real hypocrisy would be when a man is wearing pants on the street while refusing the woman to do so.

If you even check, women tend to enjoy way more advantages than men in terms of what they are allowed to do while the male can't do same so if in the aspect of proper dressing there is a projection of an idea that woman have to cover more of themselves than the men, it's certainly moderate and understandable.
