Your wedding is a festival to celebrate, a one-time celebration of a lifetime. You're getting a person for life, the better half of yours. Not just a social belief but ancestral and spiritual level bonding is to be celebrated.
The thing about money is, there are no limits up to which you can spend. You can be thrifty or overly extravagant depends on your choices, but what about the post-wedding days?
Won't the money you save of a lavish wedding be a fund which can buy comforts and securities for your family(Perhaps the new one).
Considering this, here are a set of pieces of advice to be considered...
Don't be aggressive, think smartly. An extra layered table curtain might cost just 200 but when multiplied with 50 tables, it's a considerably big expense.
Think, this day is an important day in your life, but the days to come will be even more important. For one single day, smartness doesn't commend risking your married life.
