We don't bother much about dress and manners in England, because as a nation we don't dress well and we've no manners.
-- George Bernard Shaw, "You Never Can Tell" (1898), act I
That's a surprising statement, based on movies you'd think England was the one place where dress and manners really matter.
Not that you'd notice here in Northern England, around here people think they are Dressing Up when they change from track suit to blue jeans. :-)
(I'm no fashion beacon, but at least I haven't worn track suits or blue jeans since I was a kid.)
Most people wear jeans, it doesn't make you trailer trash. I only wear a suit to the office.
Yes, Steve Jobs even wears them on stage. And maybe it's just because most people wear them that I don't like them. And to be precise, it's only blue jeans I dislike. Black, red, grey, white, or green jeans I don't mind. Heck, I've worn black and green ones myself. I just think the blue variety is so aggressively blah.
