Byrne & Bittle is a luxury baby and children’s clothing brand that encapsulates the whimsical world of children in a refined, sophisticated way. The curated collection focuses on super soft fabrics and special details for ages 3 months to 6 years. Little girls’ styles are meant for tea parties in the garden. Boys’ styles have a relaxed, yet traditional feel. Baby clothing is classic, meant for comfort of everyday napping but ready for an impromptu visit from family. Byrne & Bittle works with the top fabric mills in Italy and the world, and uses expert sourcing for their signature soft textiles. Byrne & Bittle has all the makings of a top luxury fashion brand built on a foundation of playfulness and nostalgia.

Founding Story

Based in New York City, the brand’s founder, Kristen Callahan, recognized a need in the US for sophisticated and stylish children’s clothing. For Kristen, becoming a mother reinvigorated this playful, imaginative world; a world that you want your children to live in - like playing in a secret garden, setting up a tea party in a field, or running through pastures with horses. She drew inspiration from her childhood growing up in Tennessee, her travels to the European countryside, and her time spent in and around New York City to create a collection that represented this feeling she wanted to capture - something elevated, a bit nostalgic, yet whimsical. Utilizing her know-how from a career working for some of the top luxury fashion houses in the world (Celine, Alaïa), she curated a collection of elevated childrenswear that’s luxurious, yet comfortable and meant to be lived (and played) in.
