The autumn-winter 2026-2027 fashion shows have outlined a fashion season marked by a shift in palette and a regulatory framework that changes the game for brands as well as consumers. Far from the all-pervasive black of previous seasons, the runways and search data converge towards deep shades, cuts borrowed from the men’s wardrobe, and materials that raise questions about traceability.
Brown-burgundy-plum palette: the true color shift of the season
The autumn-winter 2026 fashion trends are not limited to the bright colors highlighted by most media. Trendalytics’ analyses, published on September 1, 2026, document a shift towards what the report calls a “new heart palette.”
Deep brown replaces black as the main neutral in the wardrobe. Paired with rich burgundies and plums, it creates a range that aims to be luxurious without resorting to saturated tones.
The increase in searches around these shades confirms an underlying movement. Artistic floral prints are also gaining ground in the offering, according to the same report. Several brands present on https://fashionstores.be/ are already incorporating these colors into their fall collections.
This shift in palette raises questions about the sustainability of purchased items. A brown or burgundy coat can more easily transition through several seasons than a neon yellow piece, which aligns with a growing consumer concern for style longevity.
European anti-greenwashing directive: what changes for the “eco” look starting September 2026
The European regulatory framework will change how “eco” trends are communicated. Starting on September 27, 2026, the directive “Empowering Consumers for the Green Transition” will come into effect.
In practical terms, vague environmental claims (“eco-friendly,” “green,” “environmentally friendly”) will become illegal unless supported by verifiable evidence. For fashion brands, the constraint is direct: a jean presented as “sustainable” must be backed by documented data, not just a simple green logo.
- Labels like “eco-responsible collection” without recognized certification will disappear from product sheets
- Self-awarded labels by brands will lose all legal value in light of the directive
- Consumers gain the right to seek recourse in case of misleading claims about a garment
Field reports differ on the ability of brands to comply within deadlines. Large chains have legal teams to adapt their communications, while independent brands face a heavier compliance burden.
Oversized cuts and men’s wardrobe: beyond the fashion effect
Oversized styles and borrowings from the men’s wardrobe have occupied the runways for several seasons. The relevant question is no longer whether the trend exists, but how it concretely unfolds for the fall 2026 season.
The structured blazer with wide shoulders remains the key piece. Worn over fluid trousers or a midi skirt, it anchors a look in a defined silhouette without falling into the caricature of a suit.
The barrel jean (flared cut, high waist, wide leg) is establishing itself as the alternative to the classic straight jean. Its rounded shape at the thighs creates a contrast with fitted tops, producing a balanced silhouette.
- Pair an oversized sweater with a structured bottom (straight jean, pleated trousers) to avoid the “lost in fabric” effect
- Favor materials with structure (wool, thick twill) rather than fine jerseys that accentuate volume without sculpting
- Limit oversized pieces to one per outfit to maintain a clear silhouette reading
The available data does not allow us to conclude whether oversized styles will remain dominant beyond this season. However, loose cuts have gained enough ground in wardrobes to no longer be considered merely a runway effect.
Digital product passport: fashion traceability arrives in Europe
A less visible but structural change is underway. The European Union is working on a digital passport for textile products, which will require brands to provide detailed information about the composition, origin of materials, and environmental footprint of each garment.
This initiative follows the anti-greenwashing directive. The goal is to allow consumers to scan a QR code on the label and access the complete history of the piece, from fiber to finished product.
For buyers composing their seasonal look, this evolution changes the framework of consideration. The choice of a dress or coat no longer rests solely on cut and color, but also on the brand’s ability to document its production chain.
European brands anticipating this framework are beginning to integrate traceability sheets into their autumn 2026 collections. Brands that do not prepare for this risk losing credibility with an increasingly discerning clientele regarding these criteria.
The fashion trends of this season can thus be read on two levels. The first, visible, concerns colors (brown, burgundy, plum), cuts (controlled oversized, men’s wardrobe), and preferred materials. The second, regulatory, redefines what a brand can claim about its products. A stylish look in 2026 depends as much on the choice of the piece as on the reliability of the claims made about it.
