Womens Clothing size guide

Measuring tips

Take your actual body measurements as they are more accurate than measuring over your clothes or shoes.

Collar: measure around the base of the neck where the collar sits.

Chest: measure the chest at the fullest part, placing the tape close up under the arms.

Waist: measure the natural waistline.

Inside Leg: measure from the crotch to where your trouser is normally worn on the shoe.

Jacket Length: measure from the centre back of your neck to your hemline. Then length measurement will vary depending on the style.

Feet: Use a ruler or tape measure to measure your foot (from the heel to the tip of your longest toe) Be sure to measure both feet. Many people have feet of different sizes. Fit to the larger of the two.
