How do I measure correctly?

Take a shirt that fits you well from your closet, place it on a table and measure the measurements as follows:

1. Length: Place the measuring tape in the middle of the neck hole and measure tightly from top to bottom to the end of the shirt.

2. Bust size: Lay the shirt straight on the table and measure the width along the chest from left to right, from armpit point to armpit point.

3. Sleeve length: Place the tape measure tightly against 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.
