How we do it!
We have two main ways we explain chest size.
1) Armpit to Armpit measurement.Half Chest measurement!
The easiest ay to select the correct size is to take an existing garment that fits you well and measure from arm pit to arm pit. As shown below.
Use this measurement to select the nearest size from the size chart show below each garment.
All shirts will have a size chart and business shirts will also show neck size.
2) Full Measurement.
To do this, you will need a friend to help to ensure the correct sizes are noted.
Measure in the places noted on the images below.
Most of our products size charts are shown in chest - armpit to armpit, however some garments, like suits show full chest measurements. These are shown as (for example) a 124cm chest. What this means, is that the size noted with the measurement of 124cm, will fit someone with a 124cm chest. It does not mean the shirt measures a 124cm, it means if you measure a 124-ish chest - this is the size for you!
If you measure your chest, and get around a 122 - 125cm chest.. pick a size 124cm chest and it should fit you well.
Your neck should be measured around where your collar will go on your neck (like the image below shows) Ensure you leave a little slack with a fingers width of room .. so you can breath :-)
Simply measure around your belt line. Also try to measure your waist over your skin not over top of a belt or garment. Take the measurement when the tape is firmly around your waist.
