How to measure

Your waist is just above your belly button, between your bottom ribs and pelvic bones. Take a deep breath, keep your abs flat, and pull the tape measure tight around your waist. Use this number to choose your waist size below. 

Remember, we offer free shipping, free exchanges, and free returns, so even if you get the wrong size, we'll do whatever it takes to get you in a pair that fits perfectly.
