Sorry to correct you but Hijab doesn't make anyone prettier or uglier. The girl i love doesn't use it, in Morocco, only the old ladies use hijab.

Hijab may make them look misterious but never pretty or ugly, it also may help them to show other points of attraction besides de physicall body, but, than, if they can't go out with men, it wont help.

Only God Can Judge Me
الله فقط يمكنه محاكمتي

I am you and you are me, if you love i love, if you suffer i suffer
أنا أنت, و أنت أنا, إذا أحببت نفسك أحببت نفسي, إذا عانيتَ عانيتُ
