Two princesses, a royal dressmaker and a row about a wedding gown

Queen's dressmaker's private documents and scrapbooks detailing furore over Princess Margaret's wedding dress are up for sale

Drawings and legal documents that once belonged to the Queen's former dressmaker Sir Norman Hartnell have revealed details of a row that rocked the House of Windsor and his own illustrious fashion house 60 years ago.

A rediscovered bundle of private papers and scrapbooks, to be auctioned next month, also includes previously unseen designs by Hartnell created for Princess Anne. The colours are amazing and very evocative of the era," said vintage fashion specialist Susan Orringe.
