The reason for writing this little wax jacket size guide for men is the fact that every gentleman's bearing and physique is rather unique - I myself have what one might diplomatically could call a distinguished pear-shaped silhouette. Earning me the rather amusing nick-name of 'llama' amongst some of my closest friends.
Given this rather personal insight, I thought it 'suitable' to provide a comprehensive wax jacket size guide for men selecting your new wax jacket as they aren't always readily available for trying at the shop on the corner.

General fitting notes to take into account
Before delving into my wax jacket size guide for men and the different brands, do be aware that wax jackets should allow a fair amount of room for layering. One ought to comfortably accommodate a chunky woollen jumper or other obscure garments, particularly during the colder months of autumn and spring. When measuring, ensure the sleeve reaches your wrist bone with your arm relaxed at your side.

Measuring Yourself
For the most accurate fit:
1. Measure your chest at the fullest point, keeping the tape measure level
2. For waist measurement, measure around your natural waistline
3. When in doubt, compare measurements to a wax jacket you already own and favour
