There is nothing wrong in beautifying one's self within the boundaries of Islam. Our Prophet was a man who took great care of his appearance and cleanliness and.The proof is in the hadiths: Someone once approached the Prophet (peace be upon him) and asked: “What if someone likes that his clothing and his shoes are beautiful?” The Prophet (peace be upon him) replied: “Allah loves to see the affects of His grace upon His servant.” [Sunan al-Tirmidhī (2819)]
And : Prophet Muhammad (peace be upon him) said: “Allah is beautiful and He loves beauty.” [Sahīh Muslim (911)]
But arrogance and pride is forbidden in Islam in all situations. The Prophet warned : "one will not enter paradise if one has an atoms worth of pride in his/her heart" and Allah says in the Quran " verrily Allah likes not each arrogant boaster"
