Bust (1): Take the measurement over the fullest part of your bust.

Waist (2): Measure around the narrowest part of your waistline.

Hips (3): Measure around the fullest part of your hips.

Outer Leg (4): This is the measurement you’ll need to determine which trouser leg length you need. With your leg stretched out, measure from the hip to the sole of your foot. A little tip for you: women who are about 165-172cm generally have an outer leg measurement of 32. Any taller than 172cm is size 34, and any smaller than 165cm is 30.

Inner Leg (4): This is the other measurement you’ll need to determine which trouser leg length you need. With your leg stretched out, measure the inside of your leg from the crotch to the ankle bone.

Bust (1): Measure around the fullest part of your bust.

Under bust (2): Measure around your chest directly under your bust.

Waist (3):

Hips (4): Measure around the widest part.

To identify your bra size, you have to measure the bust at the fullest part.
If you measure in cm, the difference between the fullest part and the underbust measurement shows you the correct cup size.
If you measure in inches, you have to subtract the bra size in inches from the fullest part measurement. For example: If your underbust measures 26.8 inches (68 cm) and the fullest part of your bust measures 32.7 inches (83 cm), you need size 32B (the difference between the two measures is 15 cm which gives you a cup size of B).
