i wore an A-line kameez with pants to my brothers valima. it had 3/4 sleeves because my arms had gotten a little chunky. but i got soooo many compliments. it was made by bunto kazmi. to the mehndi i wore my valima angarka...it was cut a bit bigger so it covered alot. to the wedding i wore an old sharara and a top which i had gotten as an extra during my own wedding. i didn't want to order too many new clothes for my bros wedding so i did the best with what i had. the only new maternity outfit was the bunto kazmi one i wore to the valima. later i got it altered to fit me now and it still looks stunning! if it is a friends wedding you could also wear something of your moms. that is what my SIL did on my sisters wedding.
