Which site did you get it from? I got it from Quran.com
Sahih international (the translation closest to the arabic)
And tell the believing women to reduce [some] of their vision and guard their private parts and not expose their adornment except that which [necessarily] appears thereof and to wrap [a portion of] their headcovers over their chests and not expose their adornment except to their husbands, their fathers, their husbands' fathers, their sons, their husbands' sons, their brothers, their brothers' sons, their sisters' sons, their women, that which their right hands possess, or those male attendants having no physical desire, or children who are not yet aware of the private aspects of women. And let them not stamp their feet to make known what they conceal of their adornment. And turn to Allah in repentance, all of you, O believers, that you might succeed.
This ayat is for general situations for girls. There are different ayats concerning unsafe situations and specially for Prohet Mohammed's ladies. But this ayat is for ordinary women in safe neighborhoods. For older women who are past the age of marriage, there are different rules. Anyway this ayat is for girls and those who are in the marriage age:
- modesty of gaze
- cover private parts, chest
- Dress modestly, don't expose ornaments except to relatives (avoid exhibitionism).
All that is required ^
