“The most blessed marriage (nikah) is the one with the least expenses.”

I was wondering if you spend money on mehndi, milka, dresses, furniture.. does it count. Because technically you are not spending the money on the nikah, its on different stuff before and after the nikah. If it does count, do you have a smart idea on how to avoid all those expenses and still have a good wedding. Because parents want a function (milka/mehndi) to invite all friends and family, and you need some new dresses to dress up after the wedding, etc .. everything seems unavoidable.
