For these shirts, we recommend you measure around your neck and order the shirt size accordingly in inches. Please note we allow an additional 0.5"-1" of fabric on these shirts to allow for shrinkage. 

When ordering a separate collar we recommend buying the collar 1/2" larger. If you usually take a 15.5in shirt neck size you would need to order a 16in collar.
