agnès b. Launches Kids Line Collaboration Collection with Painter-Artist Mayumi Yamase

agnès b. will launch a collaboration collection with painter-artist Mayumi Yamase for its kids line 'agnès b. enfant' on Wednesday, July 29, 2026.

For Mayumi Yamase, agnès b. holds a special place—she once worked at the brand’s shop in London’s Covent Garden and has worn agnès b. clothing since childhood. Since 2024, the brand’s kids membership program 'Les copains!!' has featured original gift wrapping designed by Yamase.

This collection features Yamase’s original artwork applied to agnès b.’s kids and baby items. The iconic Cardigan Pression showcases a bold back print of a drawing created specifically for this collaboration. Short-sleeve and long-sleeve T-shirts, as well as baby combinaisons, each feature unique artworks, creating a playful lineup. The collection also includes a baby blanket and bib—perfect as baby gifts. This is a special collection where art and fashion naturally blend.
