3. Mainbocher

As the interwar period and Great Depression began to grip the western world, fashion was suffocated by society's lack of money. However, that didn't stop one American influence from storming through Paris. Mainbocher was an American fashion label pioneered by Main Rousseau Bocher. With a name like that, it's no wonder he was so successful in France! His fashions drew quite a lot of attention worldwide thanks to Wallis Simpson wearing them regularly. He brought nipped waists to the forefront of the fashion world, which still grace our closets today.
