How Tight Should a Dress Shirt Collar Be?

A dress shirt collar should sit close enough to frame the tie comfortably. With the top button fastened, try sliding one finger under the collar without forcing it. The finger check is a starting point, since collar shape and fabric affect how it feels.

Wear the collar buttoned for a few minutes. Sit, turn your head and look down as if you were reading. If the edge presses into your neck or you keep tugging at it, try the next neck size.

Signs the collar is too loose

A large gap at the front or sides can make the tie knot look as though it is floating. Try the next smaller neck size, or a different collar design if the smaller one feels restrictive.

Check the neck and body separately

A shirt can fit your neck and still be too roomy through the chest. If your usual size forces a compromise, look for a brand that sells by neck and sleeve measurement, or try a different body fit in the same neck size.
