When it comes to wedding budgets, some couples take “go big or go home” to absolutely wild levels. These jaw-dropping celebrations make even the most lavish Pinterest boards look modest by comparison.

1. Prince Charles and Princess Diana – $110 Million

The 1981 royal wedding that had 750 million people glued to their TVs cost about $110 million in today’s money. Security alone ate up a massive chunk of that budget, but honestly, when you’re inviting 3,500 guests to St. Paul’s Cathedral, you’re not exactly pinching pennies. Diana’s 25-foot train and that iconic puffed-sleeve dress became the stuff of wedding legend. Trust me, this one set the bar impossibly high for every royal wedding that followed.

2. Vanisha Mittal and Amit Bhatia – $60 Million

Six days of celebrations across two countries will definitely run up the bill. The steel heiress’s 2004 wedding included renting out the Palace of Versailles for the reception.

3. Prince William and Kate Middleton – $34 Million

Westminster Abbey provided the perfect backdrop for this 2011 fairy tale, though security costs dominated the budget once again. Kate’s Alexander McQueen dress was surprisingly reasonable at around $400,000, but when you factor in closing down central London and protecting nearly 2,000 guests, the numbers add up fast. I love how they managed to blend royal tradition with modern touches that felt authentic to them as a couple.

4. Kim Kardashian and Kanye West – $12 Million

Florence’s Forte di Belvedere became their private playground for this 2014 extravaganza. The wall of white flowers alone cost half a million dollars, and flying everyone to Italy wasn’t exactly budget-friendly either.

5. George Clooney and Amal Alamuddin – $4.6 Million

Venice provided the most romantic setting imaginable for Hollywood’s most eligible bachelor finally tying the knot in 2014. The Aman Canal Grande hotel became their headquarters, with water taxis shuttling guests around the city like something out of a movie. What I find refreshing is how they kept the guest list intimate despite the lavish location, proving that sometimes it’s about quality over quantity when it comes to your wedding party.
