SubhanAllah, May Allah protect us from this and protect our hearts from deviating from the Siratul-Mustaqeem. Ameen.
Allah (SWT) says that Shaytaan says in Surah Al-A'raf:
16. [Satan] said, "Because You have put me in error, I will surely sit in wait for them [i.e., mankind] on Your straight path (Siratakal Mustaqeem).
17. Then I will come to them from before them and from behind them and on their right and on their left, and You will not find most of them grateful [to You]."
So we must continue to make dua'a, make salah, and read the Qu'ran so we can remember Allah, and if we remember Allah, then He will remember us.
As to saying clothing has nothing to do with modesty, or advising someone that showing their bare body is natural and a normal thing. This kind of person has forgotten the Lord of the Worlds, so we should say Salaam (As Allah said in the Qur'an when passing an ignorant person Qaalu Salaam) to the jahil.
Allah (SWT) says in the Qur'an, Surah Al'Araf:
50. And the companions of the Fire will call to the companions of Paradise, "Pour upon us some water or from whatever Allah has provided for you." They will say, "Indeed, Allah has forbidden them both to the disbelievers
51. Who took their religion as distraction and amusement and whom the worldly life deluded." So today We will forget them just as they forgot the meeting of this Day (QIYAMAH) of theirs and having rejected Our verses.
Surely Allah is sufficient as a Guide and a Helper and May Allah guide and help us in the dunya, and give us the goodly provisions of the Hereafter in Jannatul Firdous Ameen
Wa Allahu Alam,
