There is a hadith that says:
لا طاعة لمخلوق في معصية الخالق
There is no obedience to a creation through disobedience to the Creator.
We cannot obey the laws of others at the cost of disobeying Almighty God. If hijab has been mandated by Almighty God, then we as His worshippers must comply to His law. So, we must not disobey God just to follow what someone else says, even if they are our parents whom we must obey. Our obedience to our parents is obligatory, but not in performing haram acts.
Clearly, in this case, the parents have a misconstrued approach to how their daughter should appear or conduct herself in public. They might be under the impression that by doing this, she will get married, but of course this is the worst way and its a very damaging approach.
The daughter should not comply with what her parents want, and respectfully decline, by explaining how unhealthy this approach is.
It's not just a matter of religion, but also on a human value and social level as well.
In Islam, attraction should not be by the gazing of onlookers, but by personality and moral qualities and righteousness.
With prayers for your success.
