I'm sorry, I am making jokes. There is a forum called "ask andy about clothes". You can go there and look at their forum on "trad" and that will explain what I am joking about. Basically there is a "traditional" amercian men's fashion and Brooks Brothers exemplifies it. Some people here (me) like to make fun of the general ethos of the style. These pants are an example of the "trad" style. Wear them with what you want but I would say that they are for a certain kind of person and this certain kind of person could be found in Hyannis Port. Old money, WASP, probably from the East coast. Not me, but maybe you.
Someone more knowledgeble than me, feel free to expand.
