hmm i disagree, if its mixed, where women are beautified and men can see them its haram.
The women would have to be covered correctly and not bautified and not dancing or making themselves noticed by the men.
I know becuase Moroccan weddings are this way. Women come dressed to impressed, even those in hijab, beautified with full makeup and start dancing, and then you have the men staring and enjoying the haramness, as i like to call it.
iv been to one asian wedding, where it was mixed. a sit down meal. Music but no dancing. But brothers and sisters were in full view of one another, the asian girls in thier best saris and outfits dressed for men who are not thier mahrams. Dressed how the should only dress for thier spouce. It was an experince.... and all that happens is the single girls n guys check each other out. That is the purpose to oggle at each other. lol
