Adele loves to experiment with texture and shape in her clothes rather than colour.

The 'Rolling in the Deep' singer prefers to dress in black so New York-based designer Barbara Tfank - who dressed Adele for the 2009 Grammys - chose to design for her "as if she were starring in a black and while movie".

Barbara told "Adele is a lioness. She has poise, taste, humour and soul. Her astonishing talent never ceases to fill me with enthusiasm. I always take her lead and know I can trust her instincts - as Adele prefers black, I design for her as if she were staring in a black and white movie. Instead of colour, I play with texture, trims, shape and illumination."

Vogue editor Anna Wintour first suggested the working relationship between singer and designer and Barbara revealed she was thrilled to collaborate with Adele on her fashion choices.

She said: "Anna Wintour had seen one of my double-faced, satin, cocktail coats and suggested I make a coat for Adele to wear to the 2009 Grammy Awards. The coat was chartreuse but, as Adele loves black, we all agreed on a black satin dress to go with the coat. Hamish Bowles, who escorted Adele to the Grammys, sees in her the quality of a Gainsborough portrait - and so we chose a 19th Century floral diamond brooch, which she wore on her decolletage."
