A fashion accessory is not just about its shape or seasonal color. Its composition, mechanical durability, and now its regulatory traceability determine its real long-term value. We are seeing an increasing gap between trendy accessories displayed in store windows and those that remain wearable, repairable, and resalable after several seasons.
Digital passport for products and accessories: what the ESPR regulation changes
The European ESPR regulation provides for the deployment of the digital product passport. This system will make accessible the exact composition, the origin of materials, repair instructions, and recycling pathways. For accessories (bags, belts, mixed-component jewelry), this means that each piece will need to carry a verifiable identity card.
We recommend prioritizing brands that already document their materials and processes. An accessory with traceable composition retains a higher resale value because the secondary buyer can verify what they are acquiring.
Specifically, a leather bag with declared tanning and provenance will stand out from a model without usable information. In the second-hand market, this transparency becomes a full-fledged selection criterion. The pieces offered on the By Julie online store illustrate this logic: accessories whose material nature is known before purchase.
Composition of trendy accessories: materials to check before purchase
The leather trend remains dominant for bags, belts, and bracelets. Full-grain leather ages, develops a patina, and can be repaired by a saddler. Reconstituted leather or polyurethane-based faux leather, on the other hand, cracks and cannot be resewn or dyed for touch-ups.
A repairable accessory relies on materials compatible with artisanal intervention. This is the first filter to apply, even before considering style.
Restriction of PFAS on water-repellent finishes
Water-repellent accessories (treated city bags, caps, certain pouches) face a specific chemical restriction at the European level. Per- and polyfluoroalkyl substances used for water-repellent treatments are gradually being regulated. An accessory whose finish relies on these compounds could lose its regulatory compliance, complicating its cross-border resale.
Before investing in a treated water-repellent accessory, we recommend checking if the manufacturer specifies the nature of the treatment applied. PFAS-free alternatives exist (natural waxes, silicone coatings) and preserve the longevity of the piece without regulatory risk.
Fashion accessories and lifespan: criteria for mechanical strength
A trendy necklace, oversized earrings, or a watch with an interchangeable strap should not be judged solely on their aesthetics. The strength of the assembly points determines whether the accessory lasts through one season or five.
- Clasps: a stainless steel lobster clasp on a necklace or bracelet withstands thousands of opening cycles. A low-quality zinc alloy clasp deforms after a few months of daily use.
- Stitches and rivets: on a leather bag or belt, stitches with waxed linen thread and solid brass rivets guarantee reparability by a craftsman. Hot gluing, on the other hand, makes any intervention impossible.
- Platings: a gold-plated jewelry piece with declared plating thickness (in microns) can be replated. A piece without thickness indication loses its coating without recourse.
The thickness of the plating and the nature of the clasp are the two technical data that separate disposable jewelry from transferable jewelry. When this information is missing from the product sheet, it is a warning signal.
Resale and residual value of accessories: anticipating the secondary market
The second-hand market for fashion accessories is growing rapidly. Bags, sunglasses, and signed jewelry resell better when their condition is documentable and their authenticity verifiable.
A resalable accessory is one whose material history is readable. This includes keeping the composition label, the certificate of authenticity when it exists, and soon the digital passport.
Extended producer responsibility and end of life
Extended producer responsibility (EPR), currently being extended to textiles and accessories in the European Union, will change the end-of-life management costs. Brands will need to contribute financially to the recycling or collection of their products. This constraint will impact the initial price of accessories, but also their design: mono-material pieces (leather only, steel only, cotton only) will be simpler and less costly to recycle than complex assemblies.
Choosing a trendy accessory in mono-material is betting on a reduced end-of-life cost and better compatibility with future sorting pathways.
Silhouette and balance: adapting the accessory to the style without succumbing to disposability
The choice of an accessory also engages the coherence of the silhouette. A chunky necklace structures the upper body. A wide belt reshapes the waist. Well-proportioned sunglasses anchor the look.
We observe that the most versatile pieces, those that work with multiple outfits and across several seasons, share common characteristics: simple geometric lines, neutral or muted colors, and noble materials. A black or cognac grained leather bag, a brushed steel bracelet, a pair of thick acetate sunglasses can be worn just as well with a casual look as with a structured outfit.
The signature accessory, the one that returns in your outfits regardless of the season, remains the best fashion investment. Its value does not depend on a trend cycle but on its ability to integrate sustainably into your wardrobe.
The next purchasing filter will no longer be solely aesthetic. Verifiable composition, technical reparability, regulatory compliance: these criteria already determine which accessories will retain their value in five years and which will end up at the bottom of a drawer.
