The other exhibit is THE wedding dress of the year. That worn by Kate Middleton when, in April, she married Prince William and became the Duchess of Cambridge.
Seeing it on display is the only way to get the full impact of the beauty - and the delicate handiwork - of this gown. Magazine pictures just don't do it justice. Delicate hand-made lace attached to the fabric with miniscule stitches, the buttons down the back and - the matching shoes.
Buckingham Palace and these two exhibitions are open the public until 3rd October, 2011.
A very good idea to save queuing and, of course, to make sure you get in is to pre-book via www.royalcollection.org.uk/
