there are things of such nature. The Holy Quran mentions useless talk. Or talking too much about others. Waiste of time, health, wealth on things of no use nor benefit. but looking good a having a sense of pride, not “pride” itself, for The God, & there is no god but Him, Who has no partners, says:
[(On the authority of Abu Hurayrah, who said that The Messenger of The God said: The God (Mighty & Sublime be He) said: Pride is My Cloak & Greatness My Robe, & he who competes with Me in respect of either of them, I shall cast into Hell-fire.)] [(Sahih Muslim)]
but caring about the way you look is a good thing. just don’t be abscessed with it.
