mehdi has to-kill-for formals...n quite pricey too though :p esp for ppl living outside pakistan, karma and HSY are totally 'rullofyed' now. ive seen a million of rip offs of their designs. so if u hav a gud budget go for mehdi.
check out his site. and look under formals. am sure you wud find alot of pretty dresses there =)
am gettin engaged inshallah on 7th of nov..n i haven't yet seen my engagement dress. it's from my in-laws.. so i have no idea what would it look like :P fingers crossed :p
