The fashion week calendar, explained
The single most confusing thing about fashion is that the clothes you see on the runway aren’t for the season you’re in — they’re for the season ahead. Here’s how the calendar actually works.
Two main seasons, shown ahead of time
The womenswear calendar runs twice a year. In February and March, designers show their Autumn/Winter (AW) collections; in September and October, they show Spring/Summer (SS). The shows happen roughly six months before the clothes reach shops, because retailers need that lead time to place orders, and factories need it to produce.
That’s why a coat can walk a runway in February (for the following autumn) and a swimsuit in September (for next spring). When you read “AW26” or “SS27,” it refers to the season the collection is *for*, not when it was shown.
Beyond the two big seasons
Menswear has its own dedicated shows, typically in January and June. Haute couture — made-to-measure, largely in Paris — shows in January and July. And between the main seasons, houses present commercial “resort” (or “cruise”) and “pre-fall” collections, which quietly account for a large share of luxury sales.
In recent years the traditional “show months ahead” model has loosened, with some brands moving to “see now, buy now” in-season shows and standalone destination showcases.
The order within a season
Each season the Big Four run in a fixed sequence — New York, London, Milan, Paris — across about four weeks, with the emerging and regional weeks slotting around them through the year. The Cast Index maps this whole circuit, established and emerging, on its Fashion Weeks calendar.
