I did this video last year. I will do a quick summary of the points:
-No where in the Quran or in any authentic hadith does it command women women to wear hijab, niqab, burka, jilbaab etc.
-Allah does mention khimar (a type of head covering) in the Quran. He mentions it because it was already worn by Arab women. It was already in existence before Islam was revealed. Allah mentioning this is not the same as him commanding it. Read that again if you must. Mentioning something does not equal a command. Again, Allah only mentions it because it was already worn by the women at the time. Arab culture and Arab customs does not mean it is mandatory for all Muslims to follow.
-There is no authentic hadith that commands hijab, niqab, jilbab, burka etc. There is a hadith where the Prophet pbuh told a woman that she must cover everything except her hands and face, but this hadith is weak. There are authentic hadiths about what the Prophet's wives did in regards to covering their heads and faces, but that was their own personal sunnah. Sunnah is not fardh.
-Historical Muslim cultures, such as the subcontinent (which includes the countries of Pakistan, India, and Bangladesh) never had a concept of hijab, niqab, jilbab, burka etc. This is why to this day, the majority of Muslim women in Pakistan, India, and Bangladesh do not cover their heads. Even in rural areas of these countries where globalization and liberalism hasn't been able to reach yet, it is common to see women with their heads uncovered. Yes, the British did colonize the subcontinent. But they left culture and religion to the locals. This is why Muslim (and Hindu and Sikh) women in the Pakistan, India, and Bangladesh still wear their traditional shalwaar khameez and saari clothes; clothes that have been worn by women in this subcontinent for thousands of years.
-The general idea is for women to be modest. Modesty varies by culture, place, and time. However, modesty always includes the idea that women must cover their breasts, butt, vagina, legs, and any seductive/sexual behaviour. The latter can be done by women who are either completey naked or covered head to toe in hijab, jilbaab, burka, niqab etc. An example of this is twerking. This can be done by naked women, or by women who are wearing hijab. Another example is zina (adultery or fornication). Naked women can do it, and we know that Muslim women in hijab engage in zina in our countries back home (as do Muslim men of course).
-The above mentioned aspects of modesty is necessary because this is what we men like to see. We men get aroused at a woman's breasts, butt, vagina, legs, and sexual or seductive behaviour. This is what horny teen boys search for on their smart phones and computers. We men do not get sexually aroused simply at the sight of a woman's face, hair, arms, or feet (there is an ijma by the way that a woman's feet is not awrah by traditional conservative scholars). We men and horny teen boys enjoy seeing women's private parts. We also enjoy sexual/seductive behaviour by women who are completely covered in hijab, or completely naked.
-There is a difference between women who happen to be curvy (have bigger breasts, butt, hips) and women who purposely show off their body. Don't forget this. Similarily, the clothing of women changes by culture to culture. Just because it is different from yours, it doesn't mean it is haraam. It is just different.
Dr. Shabir Ally is a well known scholar of Islam. He had defended Islam for decades from aggressive Islamophobes. He has converted many people to Islam as well. Here is his answer as to why hijab is not compulsory:
