I often find that, even though it's changing now, to dress for business and other formal affairs, they say you need a suit and tie. However, look at many old pictures and you will often see kids and average people walking around in suits and ties around the early 20th century.
So, when you're asked to wear a suit and tie to a formal occasion today, is it because it's a classy thing to do, or is it something that older people want younger people to do because that's how they used to dress normally?
I think what I'm saying is, looking at those old pictures, how the hell would you dress for a job interview? You'd pretty much come in what you wore everyday, lol, if all you do is wear a suit out everyday.
