US regular and plus size measurements for women are based on bust, waist, and hip measurements. According to the Women's US Size Chart, these measurements are typically given in inches and can vary slightly between brands. Always check the product sizing given in the descriptions for an accurate measurement of the product provided by the manufacturer.

How to Measure Your Size

The key to determine correct clothing size, is taking correct measurements. It is important to know exactly how to measure your body, and to do it carefully.  Measure Bust, Waist, and Hips using a flexible measuring tape and use the size charts to determine the correct size to purchase.

Bust: measure circumference around body over the fullest part of the bust, while wearing a correct fitting bra. Make sure the measuring tape is parallel with the floor all the way around.

Waist: Measure circumference around body at your natural waistline. Your waistline is the narrowest/slimmest part of torso (see illustration above). Note: Waist measurement is a reference measurement. So make sure to measure at the point where torso is slimmest, and NOT where i.e. you want your pants to sit (this is a usual mistake). Still not sure where you waistline is? Stand in front of a mirror, and bend to one side. Your waistline is simply where you can see a natural indentation in torso on this side.

Hips (Seat): Measure circumference of seat at fullest part of your hips.
