To resist the provocation, you must not look. 

Surah An-Noor:
Verse 30:
قُلْ لِلْمُؤْمِنِينَ يَغُضُّوا مِنْ أَبْصَارِهِمْ وَيَحْفَظُوا فُرُوجَهُمْ ۚ ذَٰلِكَ أَزْكَىٰ لَهُمْ ۗ إِنَّ اللَّهَ خَبِيرٌ بِمَا يَصْنَعُونَ
Tell the believing men to lower their gaze (from looking at forbidden things), and protect their private parts (from illegal sexual acts, etc.). That is purer for them. Verily, Allah is All-Aware of what they do.

يَا بَنِي آدَمَ قَدْ أَنْزَلْنَا عَلَيْكُمْ لِبَاسًا يُوَارِي سَوْآتِكُمْ وَرِيشًا ۖ وَلِبَاسُ التَّقْوَىٰ ذَٰلِكَ خَيْرٌ ۚ ذَٰلِكَ مِنْ آيَاتِ اللَّهِ لَعَلَّهُمْ يَذَّكَّرُونَ
O Children of Adam! We have bestowed raiment upon you to cover yourselves (screen your private parts, etc.) and as an adornment, and the raiment of righteousness, that is better. Such are among the Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.) of Allah, that they may remember (i.e. leave falsehood and follow truth).
Verse 27:
يَا بَنِي آدَمَ لَا يَفْتِنَنَّكُمُ الشَّيْطَانُ كَمَا أَخْرَجَ أَبَوَيْكُمْ مِنَ الْجَنَّةِ يَنْزِعُ عَنْهُمَا لِبَاسَهُمَا لِيُرِيَهُمَا سَوْآتِهِمَا ۗ إِنَّهُ يَرَاكُمْ هُوَ وَقَبِيلُهُ مِنْ حَيْثُ لَا تَرَوْنَهُمْ ۗ إِنَّا جَعَلْنَا الشَّيَاطِينَ أَوْلِيَاءَ لِلَّذِينَ لَا يُؤْمِنُونَ
O Children of Adam! Let not Shaitan (Satan) deceive you, as he got your parents (Adam and Eve) out of Paradise, stripping them of their clothes, to show them their private parts. Verily, he and Qabiluhu (his soldiers from the jinns or his tribe) see you from where you cannot see them. Verily, We made the Shayatin (devils) Auliya' (helpers) for those who believe not.
