Why You Should Know Your Underwear Size

Wearing the correct underwear size isn’t just about looking good—it’s about comfort, health, and confidence. Ill-fitting underwear can cause:

• Chafing or irritation

• Bunching or sagging

• Digging into the skin

• Unwanted panty lines under clothing

A proper fit ensures your underwear moves with your body, stays in place, and provides the right amount of support.

How to Measure Yourself for Underwear

Before checking any size chart, it’s important to measure your body properly. Here’s how:

1. Waist Measurement

Use a soft measuring tape and wrap it around the narrowest part of your torso, just above your belly button. Don’t suck in your stomach—stand naturally for the most accurate result.

2. Hip Measurement

Wrap the tape around the fullest part of your hips and buttocks. Ensure the tape is level and snug, but not too tight.

Tip: Measure yourself in underwear or thin clothing for the most precise measurements.

Style Matters: Different Fits for Different Cuts

Just like jeans, underwear styles can impact how a size fits. Here’s how different underwear styles may feel:

• Briefs: Offer the most coverage and are typically true to size.

• Bikinis: Sit lower on the waist and may run smaller.

• Hipsters: Fit snug around the hips with moderate coverage.

• Thongs: Less fabric, minimal coverage—some may prefer to size up for comfort.

• Boyshorts: Offer full coverage and a relaxed fit; ideal for loungewear.

Knowing your preferred style and matching it with the correct size ensures maximum comfort.

Additional Tips for Choosing the Right Size

• If between sizes, go up for more comfort, especially in tighter styles.

• Fabric types matter: Cotton stretches more than lace or mesh.

• Always try them on (over another pair if possible) before removing tags.

• Read reviews: Customer feedback often provides insight into sizing accuracy.

• Take new measurements every few months, especially if your weight has changed or during/post-pregnancy.

How to Maintain the Fit

Once you’ve found the perfect underwear, maintaining it is key:

• Wash in cold water to avoid shrinking.

• Air-dry instead of using a dryer.

• Use mesh laundry bags for delicate fabrics like lace and silk.

Proper care helps your underwear retain its size, elasticity, and shape over time.

Shop Smart: Size Charts Save Time & Money

Whether you shop online or in-store, having access to a women underwear size chart prevents the hassle of returns and exchanges. Use your measurements and refer to the chart to confidently order underwear that fits right the first time.
