Hi. My name is Ziva and my mum, Patricia, modeled for Cojana throughout the '60's. I thought I'd update you with some info you might be interested in!
Cojana employed 4 permanent models, 2 'tall' and 2 'petite'. My mum was one of the 'talls' at 5'8. The petites were 5'2.
They were a German/Jewish family headed by "Oncle Jacoby". The company was run by his nephew, Hans Jacoby. His nephew, Ernest, was part of the company and Hans' brother-in-law, Henry Chambre, was a fabric buyer. The showroom was at 10 Poland Street in Soho and the factory (at the time my mum worked there) was in Shoreditch.
Buyers came from all over the country including Harrods and Fortnum and Mason. 'Mr Hans' used to go to Paris every year to buy 'toilles' (patterns) from Chrisian Dior, Chanel etc. They would be made up on the permanent models and there would be fashion shows in the Poland Street showroom 3 times daily, 9.30, 12.30 and 3.30, to buyers for 6-9 weeks each season.
Hope you enjoyed the info!
