Is this the most over-the-top wedding dress ever? Ousted Barclays boss Bob Diamond still has money to burn as he throws lavish three-day extravaganza for his daughter in South of France

The 25-year-old wore a princess-worthy gown with an enormous train designed by Olivier Theyskens, who recently left his post as artistic director of the fashion house Theory. Her stunning strapless white dress, which was made from 35 meters of silk, featured a sweetheart neckline and was embroidered with delicate feathered fern designs. Not so delicate was the 15-foot-long train, which was so expansive it required two people to carry it.
