Dear Denier is a Danish lingerie and activewear brand with a strong sustainability profile in third-party ratings. Good On You rates it “Great” overall, with high marks for planet, people, and animal welfare. The brand is described as using a high share of lower-impact materials, recycled packaging, sea freight instead of air freight, and circular design ideas across the product life cycle. It also appears to trace most of its supply chain and to pay living wages in final production. Some wool is certified to the Responsible Wool Standard, and the brand has a B Corp certification listed by Good On You. Public review data is limited, but Trustpilot shows a mixed-to-poor score for its website domain.
Positive Sentiment Found
Public sustainability sentiment is mostly positive. Good On You rates Dear Denier “Great” overall, with a 5 out of 5 for Planet, 4 out of 5 for People, and 4 out of 5 for Animals. Its review explains that the brand uses a high share of lower-impact materials, embeds circular ideas across the product life cycle, ships by sea instead of air, and uses recycled packaging. Good On You also notes that some wool is certified by the Responsible Wool Standard, which is a third-party standard for wool welfare and land care. The Commons Earth also lists Dear Denier among expert-rated brands, which adds another positive signal, although it does not give a Dear Denier-specific score in the material shown.
Common Criticisms:
The main negative signal in the available material comes from Trustpilot. The deardenier.com Trustpilot page shows a score of 2.3 out of 5 based on 51 reviews, which points to weak customer sentiment on that platform. The snippet does not explain the reasons for the low score, so it is not possible to say whether the complaints were about sustainability, product quality, service, or something else. There is also limited public evidence in the material about full supply-chain transparency, because Good On You says the brand traces most of its supply chain rather than all of it, and it says living wages are confirmed only in the final production stage, not across the whole chain. That means some parts of the picture are still not fully public.
