Things to Remember

Waist

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

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.
