Measuring Tips

Determine your waist, hip, and thigh measurements with the help of our measuring tips. Then find your jean sizes in the charts below.

Things to Remember

Choose your maternity size based on your pre-pregnancy size. The maternity sizing allows room for a standard weight gain of 25-30 pounds.

Waist

Measure around the natural waist, keeping the tape measure taut.

Hips

Stand with your heels together and measure around the fullest part of your hips.

Inseam

Measure from crotch to floor- barefoot. Inseam is same length across all sizes. Choose between regular and exclusive inseams to find the right fit for you. Garment  inseams are in product descriptions.
