Definitions behind the T-Fashion Runway Index: looks, share of looks, change against the same season a year earlier, rising and fading, coverage by fashion week and how to cite the data.
Definitions
- Look
- One ready-to-wear runway outfit, photographed at the show. Accessories, couture and bridal shows are not counted.
- Trend
- A key item, theme, color, pattern or fabric that T-Fashion tags on each look.
- Share of looks
- Looks that carry the trend, divided by all looks of the same season, gender and fashion week scope.
- Change
- The share of looks this season minus the share in the same season one year earlier, in percentage points.
- Rising and fading
- Rising means the share grew by 10% or more on the year. Fading means it fell by 10% or more. New means no comparable data from the year before.
- Designers
- The number of brands that showed the trend in at least one look.
Example: a trend in 300 of 2,500 looks has a share of 12.0%. If its share was 4.0% a year earlier, the change is +8.0 points and the trend is rising. A trend page needs 30 or more looks from 8 or more designers.

Questions
- Why do some trends have no page?
- A trend gets a page when at least 30 looks from 8 or more designers carry it in the scope. Smaller signals stay in the platform.
- Why are city and all-cities numbers different?
- Each scope has its own denominator. A trend can take a large share of one city and a small share of the whole season.
- Why is the change in points, not percent?
- A trend that moves from 0.5% to 2% of looks has quadrupled, but it is still rare. Percentage points show how much of the runway actually changed.
- How are the photos chosen?
- Up to 16 looks per trend, spread across as many designers as possible. Designer pages show looks spread from the first to the last of the show.
