Bob Diamond gets her 25-year-old daughter, Nell, an extravagant wedding dress. The dress was made of 35 meters of silk and had a sweetheart neckline. The Olivier Theyskens design swept behind her for yards as her father, famous multi-millionaire banker, walked her up to the aisle.

Bob Diamond's daughter wore two different dresses for her lavish wedding ceremony. The first dress was the princess-like gown designed by Olivier Theyskens that has a massive train. Theyskens has recently left his position as artistic director of the known fashion house, Theory.

Taking a closer look at the famous Nell Diamond wedding dress, it was a stunning strapless white dress. It featured a sweetheart neckline and was embroidered with feathered designs. The 15-foot-long train, on the other hand, was not delicate at all. It was ultimately expansive as it required multiple people to carry it just so the bride could walk around. A long transparent veil completed her elegant bridal ensemble.

It is believed that Bob Diamond's daughter only paid for the materials and the labor, without the actual mark-up for the design. The custom-made dress was most likely worth $250,000 to $300,000.

The wedding took place at the Hotel Du Cap-Eden-Roc, which is located in the South of France. In this venue, prices start at a painful £700 per night. Bob Diamond certainly made sure that his precious little princess was treated like a queen on the most special day of her life, sparing no expense at all. He even hired the same wedding planners that were employed at Prince William's and Duchess Kate's Buckingham Palace reception back in 2011.

Moreover, the background to the reception was breathtaking as the Mediterranean was only a stone's throw from the resort.

The guests were invited to pick wedding gifts from a list that has been provided. The list includes a £2,866 bar trolley, £400 blender, and a £415 salad bowl.
