Another suggestion is to look at more SWD type brands if you're looking for pants that aren't so formal. Some examples are Lemaire, helmut Lang, zam b, etc. I do like those in comparison to most dress pants here in CM.
Not sure about a joke using the foobinacci sequence but there are fibonacci numbers too. So 11 should be a foobinacci number, the number of suits required from a tailor before you can know if he's good or not.
When I read Foo's initial post, I thought I had similar sentiments but from his later posts, maybe not. For me, it is that the forums are filled with affiliate vendor threads with hundreds of posts but nearly all of which essentially consists of a circlejerk saying "Yaay!!" in response to a vendor saying "Here is a great new product I am selling you!" For me, I have no problem with people like David, which I guess is where I differ with Foo.
