Because the straight-point collar was the collar shape gracing most military-issued dress shirts since WW I, it has long been the foundation of the modern man’s dress shirt wardrobe.
As the most stylistically neutral of all collars, the straight-point collar can be worn with any kind of suit or sport jacket. Ideally, its collar points should finish between 2 ¾ inches and 3 3/8 inches in length.
