Broad shoulders and slim skirts reflected designer Anthony Vaccarello’s intention to create a ‘simplicity of silhouette’

Saint Laurent has cross-generational cool. On the last night of Paris fashion week, Kate Moss sat next to Catherine Deneuve, both in black tailoring, sheer blouses and high heels. Pedro Almodóvar and Rossy de Palma smiled for the cameras, while Hailey Bieber and Charli XCX kept their shades on.

Saint Laurent’s daytime silhouette this season is an inverted triangle, with broad shoulders narrowing to slim skirts and sheer tights. For evening, it flipped upside down, with slinky sweaters and grand ball skirts. The colours were of cocktail ring gemstones: emerald, sapphire, ruby and garnet.

Fashion week also brings Louis Vuitton showcasing cinematic romance of train travel

Chanel came gift-wrapped in black ribbon at Paris fashion week. The ribbon was made of steel, not silk. It was the width of a city street and 368 metres long, soaring skywards beside the long catwalk like very pretty scaffolding. The message: the house of Chanel is as tough as it is chic.

New designer Matthieu Blazy is expected to take up his role next month, by which time Chanel will have been without a creative lead for almost a year. This design vacuum poses a challenge for the house, but Chanel still has a star designer – albeit one who has been dead for 54 years.
