If you have never had bespoke clothing made (or never made garments), then you may not be aware of all the body measurements that need to be taken. Luckily there are photos from Monza of the lovely Vettel and Kobayashi having their measurements taken. So, let’s go over them yeah?
Front length:
This is a torso measurement taken from the collar drop. The same measurement should be taken at the back at the neck.
Back shoulder width:
This is taken at the top of the shoulder cap. Vettel is distracted by the camera, but if you ever have your measurements taken, you are supposed to look straight ahead to avoid any distortion whilst measuring.
The same measurement should also be taken from the front. The front and back widths are not necessarily the same due to posture.
Waist measurement:
The waist is taken at the “natural” waistline, which is below the ribcage. Forget all that low-rise nonsense. 
Hip measurements are also taken.
Chest/bust measurement:
This is fairly obvious, but on women measure at the fullest point (though that is irrelevant here!).
Arm length:
Actually two types of length measurements are taken. One is the bent arm measurement, as shown by Kobayashi. The other is measuring the length while the arm is resting naturally at the side. Sometimes the distance to the elbow is also taken.
Neck size:
Men are probably familiar with this one as they buy dress shirts according to neck size.
Leg length:
Depending on what is being made, different leg length measurements on the outside of the leg and the inside. By inside, I mean the inside leg aka “inseam.” And yes… Seb’s jeans are too long. From the amount of bunching fabric at his ankle, I bet Seb’s inseam is only 30-31 inches as most designer jeans have an inseam length of 33-34.”
Of course all this precious work must be logged down. Look at Kobayashi’s vital statistics:
These are just the most basic measurements, there are a few other technical ones that I won’t get into. Hopefully this wasn’t too boring of an entry.
