THIS fly-on-the-wall documentary provides a fascinating insight into the workings of the Christian Dior fashion house and pays tribute to its skilful seamstresses, who are the real stars of the film.

Director Frederic Tcheng captures the tension and high drama in this account of new artistic director Raf Simons’s arrival to Dior in 2012.

Following John Galliano’s controversial departure, Simons has just eight weeks instead of six months to stage his first haute couture collection in what is a nail-biting race against time.

But what’s truly striking is the dedicated group of women who bring his vision to life.

They still hand-sew every garment and many of them have been working at Dior for more than 40 years, a remarkable timespan these days. Such a focus humanises and makes this exclusive world engaging to non-fashionistas.
