According to RoyalCentral, Kelly’s bouquet was particularly noteworthy.

It featured a bodice covered in delicately hand-sewn Brussels lace and pearls along with a long train.

The dress has since become an iconic symbol of bridal style.

Joe Hong, a designer for Neiman Marcus, created the looks for the bridesmaids and flower girls.

Instead of wearing a tuxedo, he opted to wear a full military uniform.

However, rather than wearing a traditional, standard uniform, Rainier actually designed his own outfit.

The extravagance didn’t stop there.

After the wedding ceremony, the couple and their guests celebrated at a grand reception.

Guests were served a decadent meal that included champagne, caviar, smoked salmon, salami, and lobster.

But the centerpiece was the wedding cake.

Things got even more extravagant when Rainier and Kelly cut the cake.

It’s hard to imagine a more dramatic romantic gesture than that!

The yacht is now called the M/Y Grace and is owned by Quasar Expeditions, a boutique holiday company.

The yacht can now be rented for a cruise of the Galapagos.

AsThe Sunreported, Grace Kelly’s suite costs a cool 17,000 to rent.
