Chest Size
The easiest way to establish your jacket/chest measurements is to look at the label inside an existing suit or jacket that you consider to be comfortable and well fitting.
In the event that you do not have a jacket to hand or are unable to locate a label, the chest measurement should be taken at the fullest point of the chest which is usually just under the arms. (NB when measuring please let your arms hang by your side).
If you have a fuller figure or a large waist in proportion to your chest then order a longer fitting waistcoat.
Jacket Length
The length of the jacket is usually proportional to your height, as follows:
Height
Fitting Length
Below 5’6"
Extra Short (XS)
Above 5’6"
5’9" Short (S)
Above 5’9"
6’0" Regular (R)
Above 6’0"
6’3" Long (L)
Above 6’3"
Extra Long (XL)
Remember that these fittings do not necessarily apply to everyone, as different people are proportioned differently - but this is a very good guide.
