Yup, the fashion-conscious male section of the English upper classes was called "the Ton" during the Regency period. People were said to have "good ton" if they were regarded as fashionable and had lots of money and good manners. The two main "styles" were the corinthian - sporty guys with "sober" but very expensive dress - and the dandies, who wore extreme clothes and looked like coxcombs. The Prince Regent tended towards dandyism. Overall, the upper class was called the Upper 10000 (or something like that).
