London Fashion Week runs September 17–21, and the most interesting names on the schedule this season aren't the ones you'd expect. Marks & Spencer is making its official on-schedule debut with a see-now-buy-now menswear and womenswear collection, and eBay is back with its Endless Runway pre-loved show. The gap between a runway and a wardrobe — including the kind of everyday heavyweight pieces we build — keeps narrowing.
Key takeaways:
- London Fashion Week takes place September 17–21, 2026.
- Alexander McQueen returns with Seán McGirr's London debut, showing menswear and womenswear for Spring/Summer 2027; Mulberry debuts under Christopher Kane.
- Marks & Spencer joins the official schedule for the first time with a see-now-buy-now collection.
- eBay's Endless Runway returns as a pre-loved fashion show, putting secondhand on the official calendar.
Why Does an M&S Runway Show Matter?
Because see-now-buy-now collapses the traditional six-month gap between a show and the shop floor. A high-street retailer on the official schedule, selling the clothes the moment they're shown, is a direct argument that fashion week's job has shifted from setting future trends to moving current product. For anyone buying clothes rather than covering them, that's the more relevant development this week.
What Does a Pre-Loved Runway Signal?
eBay staging a secondhand show on the official calendar tells you resale is no longer a sustainability footnote — it's a competing retail channel with runway-level presentation. The practical consequence for shoppers: how well a garment survives is becoming part of its value. A heavyweight piece that holds its shape for five years now has a second life and a resale price; a thin one doesn't.
Who Else Is Worth Watching?
McQueen's Seán McGirr showing his London debut across menswear and womenswear is the headline creative moment, with Mulberry's Christopher Kane debut close behind. Three BFC NEWGEN recipients — Francesca Lake, Gui Rosa and Petra Fagerström — make their LFW debuts, and Barbour and Burberry keep the British outdoor-heritage thread running, which is the corner of the schedule closest to where streetwear is currently borrowing from.
