9. Donald Trump and Melenia Knaus – $2.5 million

In January 2005, millionaire Donald Trump and Slovenian model Melania Knauss tied the knot in an Episcopal Church in Palm Beach. 

Their wedding, which cost $2.5 million, was a combination of luxury and extravagance. Melania’s wedding dress was designed by Christian Dior and crafted from satin and crystals. With a total of 1,500 crystals and 89 meters of fabric, her dress weighed 22 pounds and was changed to a lighter one after dinner.

The wedding menu was lavish, featuring caviar and Cristal champagne, and the decorations were adorned with over 10,000 white roses, from the salon to the cake.
