For the perfect fit, don't just take a wild guess - take your hip measurement! That's the best way to find the perfect size for you.

Here's how to measure:

  • Stand relaxed with your feet together
  • Wrap a soft measuring tape around the widest part of your lower hip section
  • Match your measurement number to our size in the chart above
