Petit Bateau

Ever since Frenchman Pierre Vallon cut the legs off a pair of long johns to create underpants in 1918, his company Petit Bateau - named after a line in his son’s nursery rhyme - has innovated with cosy fabrics and comfy designs. Historically a childrenswear label, collaborations with pop duo MGMT and French creative hub Kitsuné have highlighted its men and women’s collections. Many celebrities are fans, including Katie Holmes and daughter Suri Cruise.
