My question is about the majlis that people do just before the marriage events starts. They particularly call it "shaadi ki majlis". In those majalis, ladies wear new clothes and get ready as if they are coming on a marriage event. Is it right to do so?vAlso, what if that day is a wiladat of aaimma and masomeen, can we still do a "shaadi ki majlis" on that day?

There is no issue in wearing new clothes and if it is day of Wiladat then should be Jashan rather than masaib
