Is it permissible for women in a Quran memorization center to remove their hijabs, wear tight clothing, put on makeup, and recite the Quran while in this state?

There is no specific dress code required for reciting the Quran, nor is it a condition to cover one's awrah for the permissibility of recitation. However, it is recommended for the reciter to cover their awrah and present themselves in a good appearance during recitation. A woman's adornment with makeup does not prevent her from reciting the Quran. Women must cover their awrah — which is from the navel to the knee — when they gather, and the covering should be such that it does not describe the size of the awrah or the color of the skin.
