What criteria allow us to distinguish a fleeting trend from a lasting movement this season? The autumn-winter collections and the spring-summer 2026 fashion shows outline clear lines, but the fashion and lifestyle landscape is also transforming under the influence of European regulations that redefine brand communication.
This article measures the season’s trends through three lenses: the pieces that truly structure wardrobes, the materials and colors that dominate searches, and the concrete impact of the anti-greenwashing directive on brand discourse.
European anti-greenwashing directive: what changes for fashion starting September 2026
Most seasonal guides list pieces to adopt without mentioning the legal framework that will change how these pieces are sold. The Directive (EU) 2024/825 “Empowering Consumers for the Green Transition” comes into effect on September 27, 2026, across the European Union.
Generic environmental claims (“eco-friendly,” “green,” “sustainable,” “environmentally friendly”) become illegal if they are not based on demonstrable environmental excellence and a recognized certification such as EU Ecolabel or Nordic Swan. Sanctions can reach several percent of revenue.
The direct consequence for consumers is a more reliable sorting: collections that communicate about their footprint will need to provide verifiable evidence. Vague labels will disappear, and brands that surfed on a “green” lifestyle positioning without certification will have to revise their discourse starting this season.
Following fashion and lifestyle trends in 2026 also means reading labels differently, consulting resources like Carnet de Tendances that decode these evolutions over the seasons.
Key pieces of the season: comparative table of women’s trends
Rather than listing dozens of micro-trends, let’s focus on the pieces that recur in collections and online searches this season.
| Piece | Dominant Style | Associated Colors | Wardrobe Versatility |
|---|---|---|---|
| Barrel jeans | Loose fit, high waist | Light blue, ecru | High (casual to semi-formal) |
| Structured blazer | Defined shoulders, straight cut | Black, burgundy, khaki | High (office, evening) |
| Flowy long dress | Light materials, leopard or floral print | Earth tones, off-white | Medium (warm season) |
| Premium military jacket | Pocket details, visible seams | Khaki, olive green, burgundy | Medium to high |
| Cut-out ballet flats | Geometric cutouts, smooth leather | Nude, black, red | Medium (mid-season) |
The barrel jeans emerge as the most transversal cut of the season. They are gradually replacing straight jeans in wardrobes, worn both with sneakers and cut-out ballet flats. The structured blazer maintains its position as a key piece, but the burgundy color gives it a more assertive character than a simple classic black.
On the other hand, the long leopard print dress remains a more divisive trend. Its adoption strongly depends on the context: very present in spring-summer looks, it loses relevance in autumn unless paired with a structured jacket.
Trending colors and materials: what the fashion shows and searches confirm
Two color families dominate this season, and their opposition structures the silhouettes.
- Warm and earthy palette: burgundy, khaki, olive green, brown. These tones dress military-inspired pieces and smooth leathers, creating a sober look that works from autumn to spring.
- Light and bright palette: off-white, butter yellow, nude. Reserved for lightweight pieces (dresses, tops, ballet flats), it provides contrast in a wardrobe dominated by dark tones.
- Bright red as an accent: used in touches (accessories, shoes, lips), red serves as a marker of elegance rather than as the main color of a complete outfit.
In terms of materials, the trio denim, smooth leather, and suede structures the wardrobe of the season according to recent fashion shows. Smooth leather extends beyond jackets to dress and skirt styles. Suede returns on short jackets and accessories, adding a texture that contrasts with the smooth surfaces of the rest of the outfit.
Leopard print: passing trend or wardrobe staple
Leopard print returns every season in one form or another. This year, it appears on more structured pieces (blazers, midi skirts) rather than on accessories. This shift towards classic cuts gives it greater longevity than the “total look” versions of previous years.
Its adoption remains more pronounced on spring-summer pieces. For autumn-winter use, leopard works better as a detail (coat lining, scarf) than as a statement piece.
Second-hand and resale: the fashion lifestyle impacting new collections
The second-hand clothing market is no longer a marginal segment. According to the ThredUp 2026 Resale Report, conducted with GlobalData and published in August 2026, the global second-hand market is experiencing growth that exceeds that of the new market. The Resale-as-a-Service (RaaS) model now allows brands to integrate resale directly into their distribution circuit.
This lifestyle trend alters the relationship with seasonal pieces. A structured blazer bought new this season has a more stable resale value than a highly patterned dress. Pieces with high versatility retain their value better in the second-hand market, guiding purchasing choices towards classic cuts available in seasonal colors.
The combination of the anti-greenwashing directive and the rise of resale pushes seasonal style towards a logic of sustainable wardrobes: fewer pieces, better chosen, with verifiable traceability. Adopting fashion trends this season also means integrating this framework of understanding into purchases.
