The Banker
One of the safest choices, the 'Banker' contrast collar exudes sophistication and success.
The Peak
Also one of the safer collar options, the 'Peak' looks best when complimented with a medium to wide tie.
The Spread
The 'Spread' is a slightly dressier collar that can make your face look a little fuller. It's a versatile option that can be worn with just about any style of suit and is best with narrow and slim ties.
The Cutaway
The 'Cutaway' collar is a slightly stiffer collar that exposes even more of the shirt than the 'Spread' and allows room for a Windsor knot tie.
