It depends on which culture you have been born and raised.

In MiddleEast/Muslim culture, girls are considered chada/uttaulo if they don't cover their head and skin. If a girl is found to have a bf, she will be stoned to death.

In our Nepali/hindu culture people are cool with girls showing their head and a little bit of skin. Sex before marriage is still a taboo, and girls will be considered chada/uttaulo if they do such things.

In western culture people are cool with all of the above.
