The fashion trends for the spring-summer 2026 season are not limited to a color palette or a few key silhouettes. Several underlying movements are reshaping how we put together an outfit, from sourcing pieces to cutting codes. Here are the areas that deserve special attention to create a truly unique look.
Genderless Cuts and Sizes in Centimeters: A Technical Shift in Ready-to-Wear
Gender-neutral clothing has left the realm of experimental luxury. Since late 2024, mid-range brands like Monki, Weekday, and certain lines from Uniqlo Europe have been offering explicitly “gender-free” capsules, with sizes indicated in centimeters rather than S/M/L. H&M Group, in its annual and sustainability report for 2024 published in March 2025, presents this direction as a sustainable development axis.

This change is not cosmetic. Switching to a centimeter measurement system alters the pattern construction: darts, armholes, and hip falls are rethought to work on varied body shapes without gendered cuts. Straight cuts dominate, shoulders are often semi-structured, and preferred materials remain thick poplins, lightweight gabardines, and jerseys with a dense enough weight to hold the line without clinging.
We observe that this approach also liberates styling: a genderless shirt worn open over a fitted tank top creates a volume contrast that classic women’s or men’s cuts do not allow as easily. For those who wish to visit the site www.legrandformat.com, the inspirations already incorporate this logic of a decompartmentalized wardrobe.

Second-Hand in Stores: A Style Lever More Than an Ethical One
Second-hand corners integrated into major retailers no longer serve only an ecological discourse. Decathlon, through its “Second Life” spaces, has found that these sections generate significant interest in more technical or vintage sport-style pieces, which are then reintegrated into urban looks.
Second-hand in stores has become a tool for stylistic curation, not just a responsible gesture. Customers find pieces that are out of production, abandoned colors, and exhausted collaborations. The result: an outfit composed partly of second-hand items gains uniqueness because it escapes the current catalog.
What This Changes in Building a Seasonal Wardrobe
Rather than renewing an entire wardrobe each season, we recommend anchoring the wardrobe on a few new basics (a straight-cut pant, a thick cotton t-shirt) and seeking high-character pieces second-hand. The uniquely printed dress, the short colorful jacket, the technical bomber from previous seasons: these elements add depth without following the classic consumption curve.
Clothing Rental for Special Occasions: The Most Underestimated Fashion Trend
Kiabi announced in June 2025 the expansion of its clothing rental offer. This offer meets a specific need: to wear a standout piece without buying it for a one-time use.
Rental changes the relationship to style risk. A long sculptural dress or a coordinated outfit in a bold color represents a high investment for a single occasion. Renting allows you to test these pieces without commitment, and especially to dare silhouettes that you would never buy.
- Formal dresses with marked volumes (puff sleeves, short trains) are among the most rented pieces, as their use remains occasional.
- Coordinated sets in seasonal colors (butter yellow, sage green, terracotta) find a second life in rental when the color goes out of style.
- Technical pieces from fashion-sport collaborations, often expensive to buy, become accessible through this channel.
For a unique look this season, renting is not a compromise. It is a strategy that expands the realm of possibilities without burdening the wardrobe.
Colors and Volumes Spring-Summer 2026: The Choices That Really Matter
The spring-summer 2026 shows confirm the dominance of saturated palettes worn in blocks rather than as accessories. Butter yellow, omnipresent since the beginning of the year, works better as a main piece (wide pants, oversized shirt) than as a subtle touch. Wearing it as a total look with different textures (matte linen below, satin poplin above) avoids a flat monochrome effect.
In terms of volumes, the oversized sweater remains a staple of the wardrobe, but its use is evolving. We see it increasingly worn partially tucked into high-waisted pants to break the massive effect. The barrel jeans, with their flared mid-calf cut, pair well with this silhouette by creating a high-low balance.
Three Piece Combinations to Favor
- Short colorful jacket over a flowing long dress: the contrast of lengths structures the silhouette without stiffening it.
- Oversized sweater tucked into beige pleated pants: the basic elevated by the volume of the top creates a bold style without accumulating strong pieces.
- Short trench worn open over a genderless set (loose t-shirt, straight gabardine pants): a layering that plays on masculine-feminine codes without forcing the trait.
The spring-summer 2026 season rewards precise choices rather than the accumulation of trends. A wardrobe built around three or four well-chosen pieces, whether new, rented, or thrifted, produces a more personal result than an entirely renewed wardrobe. Focusing on coherence between pieces matters more than multiplying purchases.
