Re: Mayoun and Mehndi together? -- Same day!
I'm a little confused, I thought you said dancing was out??? Then what dance presentations are you talking about? Here's my understanding of Mayoun & Mehndi functions (or at least how they are done in my family/sphere of influence):
Mayoun:
Is held at the bride's parents home. Usually is the day the girl gets her bridal mehndi done. The bride spends the day being pampered and primped, and usually is not dressed up at all....prior to any rasams, a milaad is held, ending with a fatiha. For the rasms, the bride is usually smeared with ubtan and fed mithai by 7 married women, and at least in my family, presented with gifts from her mami's, khala's chachi's etc....all this culminates with singing, dancing, masti etc. In old school traditional Hyderabadi customs, that same night, the bride is left at home with her parents, while the rest of the family go to the grooms place with some mithai, and his barri (sherwani, suit, watch, etc) and do some rasms there. I have not seen that particular custom observed here in our circle in the US in a long time though....
Mehndi
Is the night when the groom's family comes to the bride with her wedding attire, jewelry etc. They do their moo meetha rasm, or the thing with the paan leaf in her hand....the groom is also then teased by the bride's sisters/cousins etc and various rasms like ungli pakarna etc insue and naik is handed over.
Depending on the family's involoved...group/choreographed dancing, singing and back and forth dance off's between both sides takes place until the wee hours of the night.
Now, given those above scenarios, if you want to have a joint event and combine two in one, you could start off with a darz & dua, do the mithai feeding and yes, go straight to dinner. That would make perfect sense!
