The Ivy-looking Korean guy standard

One time I was shopping with a friend. She urged me to buy slim pants. I’ve never worn slim pants before as I like them just straight loose. She said that’s what most Korean guys like to wear and tried to explain to me. I don’t really get what she means till she showed me this picture. Ah, okay.

That is supposedly the standard look for a Korean guy who studies at an Ivy league college.
