The certified family-run businesses where the products are manufactured are located in France, Tunisia, and Portugal. These locations guarantee high production quality and responsible manufacturing that respects both the environment and the rights of the workers.
The company conducts tests with its partners to check the materials for durability and resistance to sun, water, and chlorine.
Je ne sais quoi uses recycled fibres, such as recycled polyamide, recycled polyester, and recycled lyocell (micro). The products also contain modal, elastane, and the bio-based polyamide EVO, which is used in the sets.
The brand utilises clean-cut technology and thermobonding techniques, ensuring that the underwear remains invisible from the outside. All materials are OEKO-TEX 100 certified, guaranteeing that the products are free from any toxins.
Since Je ne sais quoi primarily uses synthetic fibres, there is a risk that microplastics may be released. To prevent these particles from entering rivers and seas, COSH! recommends the use of GuppyFriend.
Most of the products are made from blended fibres. According to Je ne sais quoi, the materials are designed to be recyclable and thus become part of a circular loop.
The company “Je ne sais quoi” is based in Paris, France.
The brand focuses on production in Europe to keep its carbon footprint low. However, COSH! does not have detailed information on the transport routes, making it difficult to track the supply chain concretely.
The company does not use any animal materials in its items.
The brand takes a strong stance on body positivity by showcasing a variety of body shapes – something COSH! especially appreciates.
With only four collections per year, the team creates space for thoughtful and conscious production of high-quality items. This approach to the design process reflects their ambition to be a true slow fashion brand.
Their designs are characterised by timeless simplicity, avoiding the fast trends of the fashion world. Instead, the focus is on longevity and classic elegance. Additionally, they prioritise producing smaller quantities to avoid surplus.
On its website, Je ne sais quoi provides detailed insights into the pricing of some products, allowing customers to understand exactly what they are paying for. They also disclose which countries their products are made in, which represents a first step towards building a trusting relationship. However, a more comprehensive picture that includes further details about the production conditions and the journey of materials is still missing.
Conclusion
Je ne sais quoi is a body-positive slow fashion brand that has been producing stylish and more sustainable underwear since 2020. The high-quality briefs, menstrual underwear, bras, pyjamas, and bodysuits are made from recycled and OEKO-TEX certified materials that are free from harmful substances, offering customers both comfort and confidence.
COSH! is eager to see how Je ne sais quoi will evolve in terms of circular practices and transparency in their supply chain and looks forward to following these developments.
