In the world of shirting, there are four basic types of shirt collars. Besides enduse (casual, business or formal), shirt collars differ based on the amount of spread - the distance between the two collar points. And the reason for different spreads? Your necktie… the Four-In-Hand, Half Windsor, (full) Windsor knot, or Bow Tie.
Button Down Collar: This collar has a more casual enduse. It can be worn with or without a tie, making this choice more appropriate in a business casual setting. Perfect with a Four-In-Hand knot.

Straight Collar (Point-Collar): This is the most common collar, which can be found on most conservative business shirts. With its slight spread, this collar works best with a Four-In-Hand knot or Half Windsor.

Spread collars: This is a more formal collar. Due to the wider spread between collar points, this collar was intended for the Windsor knot.

Wing Collars: This collar is considered very formal. It was given its name based on its rather large spread creating a wing like collar. Most commonly worn with tuxedos, it is perfect for Bow Ties.
