SIREN Periodwear Sizing Guide 

To ensure the perfect fit for comfort, sculpting, and leakproof protection, it's important to measure correctly. Here’s how you can get your accurate underwear size before purchasing SIREN Periodwear:

1️⃣ Measure Your Waist

🖤 Where to measure: Wrap the measuring tape around the narrowest part of your waist (above your belly button but below your ribs).
📏 Tip: Keep the tape snug but not too tight—you should be able to breathe comfortably

2️⃣ Measure Your Hips

🖤 Where to measure: Stand with feet together and measure around the widest part of your hips and buttocks (this is usually about 7–9 inches below your waist).
📏 Tip: Ensure the tape is level all the way around for the most accurate measurement.

 

Consider Stretch & Fit

✔ SIREN’s underwear is sculpting, seamless and made with high-stretch fabric.
