Their collaboration blossomed into a dynamic working relationship, crafting many of Dame Shirley’s iconic stage outfits.

“She can really work them as well. She was quite wonderful, very natural, had great fun, sort of, organising things.

“I think with all the people that I’ve dressed, it’s a case that they look at what you do, and they come to you because they feel that you could do something that accentuates their personality and can look great.”

In Dame Zandra’s new autobiography, Iconic, Dame Shirley is quoted as saying: “We share the same sentiment. Who wants to live a life without colour, music, or laughter?”

Wales not only inspired Dame Zandra’s first collection but also immortalised her in a vibrant sculpture by close friend Andrew Logan, displayed at The Andrew Logan Museum of Sculpture in Powys.

“Andrew and I went to India, where we saw these delightful wobbling dolls. He created a huge one of me in a green crinoline with red and pink paisley,” Dame Zandra said.

“It wobbles and dances in the museum. It’s rather fabulous.”

Dame Zandra says she is most proud of the fact that she is still designing from her London studio.

Following treatment for cancer four years ago, she still has immunotherapy.

Now, the designer is making sure her work will be available for future generations to enjoy.

Her legacy endures in museums in New York, Los Angeles, and at her own Fashion and Textile Museum in London.

But what is her message for us all when we dress?

“Never be nervous of wearing colour and jewellery,” Dame Zandra said.

“It cheers you up in the world. And don’t worry if people look at you.

“You’re just a wonderful flower that passes by.”
