About Us
The Hartley Sisters is a UK-focused fashion brand operated by De Lange Services, a company based in the Netherlands. De Lange Services develops and manages The Hartley Sisters, offering women's clothing for everyday life. The brand serves customers exclusively within the United Kingdom.
While the company is registered in the Netherlands, The Hartley Sisters was built for the British market from the start. Customer service operates on UK hours and is reachable by email on every working day.
Our Story
The Hartley Sisters was created with a clear purpose: to offer women a considered selection of clothing that works beyond a single season. Rather than following fast-moving trends, we focus on pieces that earn their place in a wardrobe and stay there.
Our collection is curated with attention to fit, fabric and finish. From dresses and blouses to knitwear, trousers, skirts and outerwear, each piece is selected to reflect a balance between comfort and structure, ease and intention.
At The Hartley Sisters, style is not about excess. It is about consistency and pieces you reach for again and again.
Our Mission
Our mission is to offer women a well-curated selection of clothing that combines everyday wearability with considered design. We select each piece with attention to detail, and describe it as accurately as we can so you know what you are ordering.
We are committed to providing a seamless and reliable online shopping experience, supported by transparent communication and dependable customer service. At The Hartley Sisters, our priority is not volume, but consistency and thoughtful curation.
Our Vision
Our vision is to establish The Hartley Sisters as a trusted destination for women's fashion within the United Kingdom. We aim to build a brand known for consistency, clear communication and long-term trust.
As we grow, our focus remains on maintaining a clear identity rooted in considered design rather than temporary trends. We envision a brand that continues to evolve while staying true to its core values of reliability, transparency and thoughtful curation.
We Are Here for You
At The Hartley Sisters, we are committed not only to offering considered fashion, but also to delivering a smooth and reliable shopping experience. We value clear communication, attentive support and a service approach built on professionalism and care.
