A hotly anticipated party thrown by high-street retailer H&M and pop star Charli XCX is set to shake things up as London Fashion Week opens on Thursday alongside two shows focused on sustainability.

This year, the label headed by Alessandro Michele will be holding three shows instead of the usual five, presenting its haute couture once a year and its men's and women's ready-to-wear collections together.

It isn't easy being green, but the designer's triumphant return to Manhattan, where he lived and worked in the nineties, made it look it.

The designer celebrated a 35-year working relationship with Italian artisans with a collection his client Vice President Kamala Harris would vote 'yes' for.

Another glorious day of September weather took advantage of outdoor venues, skyscraper locations, sunbathed lofts, and the famous Apollo Theater.
