Organic Cotton

There is something wonderfully simple about organic cotton. Naturally soft, breathable and gentle against delicate skin, it is a fibre we return to again and again for its everyday comfort and enduring quality. Grown without synthetic pesticides or fertilisers, our organic cotton is chosen with both little ones and longevity in mind, creating pieces that feel beautiful from the very first wear and continue to soften and hold their shape wash after wash. Easy to care for and made for everyday adventures, it is the kind of fabric that can be lived in, loved deeply and, hopefully, passed down to the next little one. Our organic cotton is primarily sourced from trusted suppliers in India and the People's Republic of China, with some finished garments completed in Vietnam, and every batch is tested for pH, fabric performance and formaldehyde levels. Our suppliers also comply with REACH and Restricted Substances List requirements.

Cotton

A natural fibre in its simplest form, cotton has been part of our collections from the beginning for good reason. Soft, breathable and wonderfully easy to wear, it brings a sense of comfort to everyday dressing while standing up beautifully to the rhythm of little life. Its lightweight, smooth fibres are gentle against delicate skin, while its natural durability means pieces can be washed, worn, played in and loved again and again. We choose cotton for its ability to make getting dressed feel effortless, creating timeless pieces designed to stay in wardrobes for years rather than seasons. Our cotton is sourced from trusted suppliers in India and the People's Republic of China, with every batch tested for pH, fabric performance and formaldehyde levels, and our suppliers complying with REACH and Restricted Substances List requirements.

Pima Cotton

Some fabrics are soft, and then there is Pima cotton. Known for its extra-long, fine fibres, Pima cotton has an exceptionally smooth, almost silky feel, with a beautiful natural sheen that makes it feel quietly luxurious against the skin. These longer fibres also give the fabric its strength, helping it resist pilling, maintain its shape and stay beautiful through countless washes and everyday adventures. It is a fabric that feels special without asking for special treatment, making it just as lovely for everyday wear as it is for treasured pieces. Our Pima cotton is sourced from the United States and finished into garments in the People's Republic of China, with every batch tested for pH, fabric performance and formaldehyde levels and each fibre accompanied by a transaction certificate documenting its chain of custody.

Cotton Modal

For the pieces made to move, stretch, cuddle and play, our organic cotton modal brings an especially soft touch. A beautiful blend of natural cotton and modal fibres, it has a buttery, silky feel and a fluid drape that moves effortlessly with little ones throughout their day. Modal, made from beech trees, brings added softness, absorbency and flexibility, while organic cotton gives the fabric its familiar breathability and strength. The result is a beautifully comfortable fabric that is gentle against delicate skin, holds its shape and colour beautifully, and feels right at home in everyday essentials. We often use our cotton modal in ribbed styles for a little extra flexibility, with a small amount of elastane added to some high-movement pieces such as leggings. Our cotton modal is sourced from trusted suppliers in the People's Republic of China, and every batch is tested for pH, fabric performance and formaldehyde levels.

Tulle

For the moments that call for a little magic, there is tulle. Light, airy and beautifully delicate, its fine hexagonal mesh creates the soft volume and floaty movement that makes special pieces feel almost dreamlike. We choose a softer modern polyamide tulle, designed to feel gentler than traditional, stiffer versions, while still creating that beautiful sense of movement that catches the light and photographs so beautifully. Tulle is delicate by nature, which is part of its charm, and deserves a little extra care to preserve its shape and beauty. In our garments, it is thoughtfully layered over soft cotton so that it does not sit directly against delicate skin. Our tulle is sourced from trusted suppliers in the People's Republic of China, with every batch tested for pH, fabric performance and formaldehyde levels.

Merino Wool

There is a reason merino has long been treasured for little ones. Naturally soft, smooth and wonderfully clever, this beautiful New Zealand fibre helps regulate temperature, manage moisture and resist odour, keeping little bodies comfortable through changing seasons and making it especially lovely for sleep and layering. Its superfine fibres feel gentle against delicate skin, while its natural properties help create a cosy layer without overheating. We love merino for the way it works quietly in the background, keeping little ones comfortable while making life a little easier for parents too. Our merino wool comes from RWS-certified farms across New Zealand, with the Responsible Wool Standard recognising responsible animal welfare and land management practices. With the right care, merino is naturally long-lasting, and many of our pieces are made to be treasured and passed down through generations.

Leather

Beautiful things often become even more beautiful with time, and our leather is chosen with that in mind. Made from genuine cowhide, it has a natural strength and smooth finish that softens and adapts with wear, becoming more comfortable with every adventure. Unlike synthetic PU alternatives, genuine leather is naturally breathable, while its resilient fibres give it the durability to become a much-loved part of a little wardrobe for years to come. In our shoes, we pair the leather outer with a smooth leather lining for comfort and longevity, creating timeless pieces that feel just as special as they look. Our leather is sourced and finished in Indonesia, and our supplier holds an active Leather Working Group certification, reflecting recognised environmental, social and governance standards across the leather supply chain. With simple care, leather can be wiped clean and maintained for years, allowing each piece to develop its own story along the way.
