Tara O'Callaghan Millinery

With more than three decades devoted to creating distinctive hats and headpieces, Tara O’Callaghan Millinery has become a trusted name in British hat-making. Drawing on this heritage, Tara has turned her attention to the everyday essential — designing a cap that offers understated elegance while standing up to the elements.

The TO’CA Shell Cap is crafted from 100% wool marl felt, chosen for its natural character and timeless appeal. Inside, a hand-stitched organic elastic allows the cap to settle gently and securely to the wearer’s head, bringing comfort without compromising craftsmanship. Made from certified organic, biodegradable materials, it remains kind to both skin and planet.

Blending traditional techniques with a modern sensibility, the TO’CA Shell Cap embodies the quiet refinement and considered design at the heart of the brand.

Reasons to TO'CA your wardrobe...

  • Skin Protection

    Protect your skin with a TO'CA cap. The tight weave of 100% pure wool creates a natural SPF 50+ shield for your skin, ears and eyes.

  • Super comfortable

    With organic cotton and recycled rubber elastic integrated for comfort, it feels effortless to wear and quietly confident in style.

  • Easy Travel

    The pliability of the TO'CA 'Perfect Companion' allows it to be packed into a bag or suitcase and due to the gut sewn into the brim it will then spring back into shape just as soon as you need to pop it back on.
