Quick answer
To find your Lou Undies size, measure your hip at the fullest part and prioritize that number over your waist measurement on the ARQ size chart.
Why hip measurement matters more than waist
Lou Undies sit low on the hips, so the hip measurement is the best predictor of how they'll feel. If you choose based on waist size alone, you might end up with a pair that's too tight across the hips or too loose at the waistband.
The size chart at ARQ is designed with this in mind. When you look at the chart, find your hip measurement first and match it to the corresponding size. This approach works for all Lou Undies colors and styles.
Understanding the fabric stretch
Lou Undies are made from 92% organic cotton and 8% spandex. The spandex provides stretch and recovery, so the fabric will conform to your body while maintaining its shape over time.
Because of this stretch, you don't need to size up for comfort. The fabric will move with you, but it's still important to get the base size right by using your hip measurement.
Steps to find your Lou Undies size
- Measure your hips: Wrap a soft measuring tape around the fullest part of your hips and buttocks, keeping it parallel to the floor. Note the number in inches. Make sure the tape is snug but not tight.
- Compare with the size chart: Open the ARQ size chart and find the row where your hip measurement falls. That row indicates your recommended Lou Undies size. If your hip measurement falls between two sizes, choose the larger size for a more relaxed fit.
- Prioritize hip over waist: Even if your waist measurement suggests a different size, go with the size that matches your hip measurement. The low-rise cut means the hip is the critical area. If you're between sizes, size up for comfort.
