Difference between the President Spread and Londoner Collar
The President Spread is less spread than the Londoner collar and a little bit taller at the front collar band as well as at the back of the collar and it also has slightly longer point lengths. The President Spread wouldn’t be considered a “Cutaway” collar, but the Londoner collar would.
The larger size of the President collar makes it a great fit for a larger man, or for someone that just wants a slightly larger, more prominent collar. You might consider the larger size of the President collars a bit more British than American. The Londoner collar is a sharp collar that is perfect for the man who wants the cutaway European look without being too extreme.
