I wear cardigans because I look classy and cultured.

Its definitely a cultured garment as it's associated with college culture from the Roaring Twenties.

That's cool, do you know when they were first made?

I'm unsure of its earliest origins, but the earliest popularized date of the shirt I'm aware of is from the 1930s.  I'm sure it's been around for longer.
