How do I measure correctly?

Take a zip jacket that fits you well from your wardrobe, place it on a table and measure the dimensions as follows:

1. Length: Place the tape measure at the left or right shoulder point and measure tightly from top to bottom to the end of the hoodie.

2. Width: Lay the hoodie straight on the table and measure the width along the chest from left to right, from armpit to armpit.

3. Sleeve length: Place the tape measure taut at the shoulder seam and measure along the top edge to the end of the sleeve.

Sizes may vary between 2-3 centimeters as they are measured by hand.
