Re: lehnga flare of this sort …
I saw Monique Lhuillier Wedding Dresses up for resale on Pre owned wedding dresses’ website. They are sold now but they went for huge amounts as you said. Maybe they make the lace of each dress and that raises the $$$. Look here:
New with tags Monique Lhuillier Wedding Dress Tamara, Size 2
Tamara | Used Wedding Dresses | Once Wed
Used Monique Lhuillier Wedding Dress Tamara with Jucinda sash, Size 6
BTW, did you contact any Pakistani designer for the dress? I am willing to help if you want to.
