French luxury house Hermès said Wednesday that Christophe Lemaire, designer of French sportswear brand Lacoste, will replace Jean-Paul Gaultier as its women's fashion designer.

Hermès, in a statement, said Mr. Gaultier wanted to concentrate on his own brand after seven years leading Hermès' women's collection. Mr. Gaultier's last collection for the family-controlled label will be presented in October, Hermès said. Mr. Lemaire's first collection is expected next year. Hermes said it will retain its 45% stake in the Jean-Paul Gaultier brand.
