The dress Kate Middleton wore for a charity fashion show at St Andrew's University is being sold at auction. The story attached to the dress is that when she wore it Prince William apparently fell in love with her.

The see-through knitted lace dress by Charlotte Todd was originally estimated to fetch £8,000-10,000 when it goes under the hammer but is expected to fetch more because of wide international interest.

Auctioneer Kerry Taylor and designer Charlotte Todd told BBC News why this is such a special moment.
