Finding your perfect size has never been easier. Just grab a measuring tape, and in a minute, you’ll know your ideal POPFLEX fit. We’re confident in our size chart – it’s accurate and designed with real women and real customers in mind.
Here’s how to measure your body to find your best match:
- Bust: Wrap the tape around the fullest part of your chest, making sure it’s snug but not tight. This will give you your bust measurement.
- Waist: Find the narrowest part of your waist, usually just above the belly button, and measure around this area without sucking in.
- Hip: Measure around the widest part of your hips, keeping the tape parallel to the ground for the most accurate result.
Refer to our size chart below to match your measurements with your POPFLEX size:

A WAISTBAND FOR EVERY BODY

POPFLEX bottoms aren’t just anti-cameltoe with pockets, you have choices when it comes to fit!
1. Hourglass: if you want to accentuate the curves of an hourglass figure, the crisscross band will create that illusion.
2. Supersculpt: if you want a solid, no questions asked body sculpting legging, this one’s for you.
3. Cargo: if leggings always slide down on you, the drawstrings on this waistband will help.
