How do I measure correctly?
Take a blazer that fits you well from your closet, place it on a table and measure the measurements as follows:
1. Length: Place the tape measure in the center of the neckline and measure tightly from top to bottom to the end of the blazer.
2. Bust: Place the blazer flat 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.
