According to US Today, approximately more than 125,000 tickets were sold before the exhibit even opened. The exhibit is expected to draw record crowds with the Royal Collection expecting "to sell out" of their 643,000 tickets over the 10 week period. 

On display is the Duchess of Cambridge's wedding dress, shoes, earrings and a replica of her bouquet which the public can view up close. The dress itself will surprisingly not be shielded by glass, allowing for the beautiful lace detailing to be seen in all its uninterupted glory. The Daily Mail reports the cost of the dress to be at least £250,000. 

Also on display is the royal wedding cake. However, according to New York Magazine, the top layer is only a replica as this has to be saved for the royal couple's first child's christening! Don't worry though, the palace are experts in mould prevention - with some of the Royal Collection's assemblage of wedding cakes dating back to the 19th Century. 

If this sounds a little crazy to you, keep in mind that Princess Diana's dress which was designed by the Emanuel's is still touring the world today.
