Do you think Islamic"Libaas" is a must on Muslim men and women i.e important?

If The Label Shows Your Intent Wear It.

wow...

a woman needs to be covered when she is in public and with none mehrams... every scholar agrees to what that 'covering' is... headscarf... body (jilbaab thats ISNT tight).... feet

depending on what scholar you follow, some say hands and face ASWELL.

you can tell a Muslim man by there beard, which should be kept neat and tidy and not more than a fist long. moustache that is trimmed nicely and not untidy. ankles ["The izar (lower garment) of a Muslim is to the middle of the shin and there is no sin if it comes halfway between that and his ankles, but what comes lower than the ankles is in the Hell-Fire. On the Day of Resurrection Allaah will not look at a man who drags his izar out of arrogance." (Abu Daud, al-Nawawi declared it sahih)] a man's garments shouldn't be tight either so you can see the shape of there backside!
