What's the deal with those blue shirts with the white collars?

In My Humble Opinion

My husband owns a black striped dress shirt with contrasting white collar and cuffs. It’s super sexy.

For example:

At my old job, someone liked to call them “i-banker shirts” (i-banker = investment banker). I had one in grey with a white collar that my wife bought for me, but it wasn’t my style.
