Dupatta setting is VERY important Amna..and especially according to hairstyle's sometime's it REALLY bugs me when a bride has a dupatta draped the wrong way! I just wanna re-do it for her.. there are diff ways for every hairstyle be it loose curls, middle-parting or the heavy updo's. The bride has to be comfortable as well, as some dupatta's can really be heavy! And pinning them is important too, no one wants their clothes ripped or torn cuz of badly placed and not enuff pins. =)
Amna you should do all sorts of makeup, as some brides may want model makeup or engagement makeup on their baraat and valima.
