Hello Miriam,

It’s wonderful to hear about your father’s involvement in the fashion industry and his fashion shows in the late sixties with iconic models like Twiggy and Jean Shrimpton. To find photos and more information about those specific fashion shows, you might want to try the following sources:

1. Fashion Archives and Museums: You can contact fashion archives and museums in London, such as the Victoria and Albert Museum’s Fashion and Textile Collection or the Fashion Museum in Bath. They often have extensive collections of fashion photographs and documents from various eras. See https://www.vam.ac.uk/collections/fashion

2. Fashion Magazines and Newspapers: Check fashion magazines and newspapers from that time period, such as Vogue, Harper’s Bazaar, or The Times. They may have covered the fashion shows and could have photographs in their archives.

3. Online Archives: Explore online archives and databases that specialize in vintage fashion and photography. Websites like Getty Images, Alamy, and the National Portrait Gallery might have relevant photos.

Remember to provide as much detail as possible about the fashion shows, including the date, location (Mermaid Theatre in London), and the names of the models and designers involved (Twiggy, Jean Shrimpton). This will help others in your search.

If you do manage to find any photographs or information, it would be great to share them, as it could contribute to preserving the history of fashion from that era. Good luck with your search!
