London Fashion Week runs from 17 to 21 September 2026, and the collections are for spring and summer 2027. The louder part of the week belongs to debuts and streams. The quieter part, which is the part that lasts, belongs to houses with archives, to clothes made in small numbers, and to objects that are not clothes at all.
Inheritance
Two houses change hands in public this season. McQueen returns to the London schedule with Seán McGirr's first show for the house in the city, presenting menswear and womenswear. Mulberry returns under Christopher Kane, with his first collection for the label.
A creative director inheriting a British house inherits a set of codes: in McQueen's case tailoring built like armour, in Mulberry's a leather tradition that has always been more Somerset than Bond Street. The interest of a first collection is never whether it is beautiful. It is which codes the new author treats as load-bearing and which he treats as decoration.
Around them, the houses that supply the week's continuity: Burberry, Barbour, Erdem, Emilia Wickstead, Roksanda, Richard Quinn, Simone Rocha and Harris Reed. Barbour and Burberry are the two British names most often bought for reasons that have nothing to do with a season, which is the definition of heritage as an asset rather than a story.
Small numbers
Onalaja shows demi-couture: made in limited quantity, closer to the atelier than to the wholesale rail. Alongside it, two labels arriving with an established hand rather than a student portfolio - Joyce Bao, and Lovebirds from India, whose presence marks London's long habit of taking in houses formed elsewhere.
Demi-couture is the most honest category in contemporary luxury. It admits that the value is in the hours and the hand, and it does not pretend that a garment made in fifteen pieces belongs to the same economy as one made in fifteen thousand.
Stone, metal and the edit
The week's jewellery is where the quiet codes are clearest. Dover Street Market hosts a jewellery showcase in store. Harris Reed works with Missoma; Simone Rocha with Harvey Nichols. Selfridges presents an edit of British designers.
A jewellery showcase inside a shop is an old form done well: no runway, no soundtrack, an object at eye level under good light and a small number of people who came to look closely. It is also the format in which British design is strongest at the moment, because it rewards making over spectacle.
One lesson from the high street
Marks & Spencer makes its fashion week debut this season with a first exclusive runway collection, released to buy immediately, in its centenary year.
It belongs in a luxury column for one reason. A hundred-year-old brand chose an anniversary to do something it had never done, and it chose to make the clothes available the same day. Heritage that only looks backwards becomes costume; the houses that survive their own centenaries are the ones that keep finding a new use for the archive.
That is the code beneath all of the above. A house with a past is not selling the past. It is selling the confidence that comes from having made the same thing well for long enough that a change of hands is news.
