What is 'Les grands couturiers français dessinent des modèles de haute couture' when translated from French to English?

"Elevated seam" literally and "high fashion" loosely are English equivalents of the French phrase haute couture. The pronunciation of the feminine singular phrase -- which identifies the "great, lofty" impressiveness of the seams (and everything else) in customized, expensive, meticulous clothing for the powerful and wealthy -- will be "oht koo-tyoor" in French.
