Our Sizing

Men’s Formal Shirts

Here is some advice on finding your perfect fit for formal shirts:

Neck Sizes
Our Nickson formal shirts always come in a larger variety of neck sizes at smaller increments of 0.25 inches, with other brands this tends to be larger at 0.5 inch increments. By focusing on a larger size range, this naturally assists you in finding a better fit.

If you feel you need a slightly bigger collar size our sizing has more options so you can move up or down slowly. For example, a popular situation is if you’re normally a 15.5″ collar but a 16″ collar seems too much of a ‘jump up’.

Body Sizes
The body of the shirt does not increase as much as you might be used to – it focuses on a shaped fit that contours to your torso that edges up in sizing with smaller increases.

Sleeve, Collar and Body Measurements
Sleeve measurements are from the middle of the back of the neck to the wrist in inches.

Collar measurements are the neck with some excess depending on your desired comfort.

Body measurements are as UK standard – as for suits / t-shirts and regular shirts, again depending on your preference for type of fit.
