To find the right size clothing, it’s usually necessary to measure five key areas of the body. Follow these steps for accurate results:

1. Bust

With your arms relaxed at your sides, measure around the fullest part of your bust, ensuring the tape is parallel to the ground.

2. Waist

Measure around your natural waistline, typically the narrowest part of your waist.

3. Hips

Stand with your feet together and measure around the widest part of your hips, keeping the tape straight and level.

4. Leg Length

Without shoes, stand on a flat surface. Measure from the top of your hip bone down to the inside of your ankle.

5. Height

Stand barefoot against a wall with your heels, buttocks, shoulders, and back of your head touching the wall.

Measure from the floor to the top of your head.
