Does God accept the repentance of a sinner and answer their prayers, such as the repentance of a Muslim woman who wore the hijab after having displayed her adornments for forty days?

One must repent to Allah from every sin, whether minor or major, and there is no sin greater than repentance, for Allah accepts the repentance of a polytheist if he repents sincerely, and the door of repentance is open until the throes of death (ghargara) or the sun rises from its west.
