Obsidian Women's Thermal Knickers

How to Measure

1. Measure your waist first – this measurement should be taken above the hip bones, should run pretty close to the top of your belly button.

2. Women will also need to measure their hips. This measurement should be taken around the widest part of the hips.

3. From these measurements, you should be able to find your correct size.

If you are in-between sizes, weight and height can factor in, but should not be necessary.
