Brand to Know: Sunday Siblings

Sunday Siblings was founded on the Mornington Peninsula in Australia by three moms - Mia, Isabelle and Bianca - with a simple idea: to create clothing they couldn’t find for their own children.

Built around comfort, durability and playfulness, the brand focuses on pieces made to be lived in, shared and passed on - from sibling to sibling and beyond. Each design reflects real childhood: movement, colour, freedom and joy.

At its core, Sunday Siblings celebrates togetherness and the beauty of everyday moments - creating clothing that grows with children and carries stories over time.
