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.

Description
Description
A little contrast, a lot of impact.
The POPFLEX It Girl Bra uses crisp white trim to define its square neckline, wide shoulder straps and supportive underbust band.
Clean and minimal from the front with an intricately crossed open back, it brings a polished fashion-sport mood to Pilates, barre, dance and coordinated studio sets. Available from Dance World in Cosmic Navy with White and Black with White.
POPFLEX It Girl Bra – Design & Support
The open square neckline creates a clean frame across the collarbones, with contrast binding clearly defining the shape. Wide fixed straps continue over the shoulders before crossing into a layered, sculptural back.
A close underbust band provides a secure base, while the soft polyester-and-spandex fabric stretches comfortably around the body. Designed for low-to-medium-impact support, it is particularly well suited to Pilates, barre, conditioning and dance.
Inside, POPFLEX’s Nip Cushion layer provides discreet coverage beneath the smooth fabric. Removable pads can be retained for additional shape or removed for a softer, more natural profile.
Why You’ll Love It
- ♡ Contrast Square Neckline
- ♡ Sculptural Criss-Cross Back
- ♡ Secure Underbust Band
- ♡ Low-to-Medium-Impact Support
- ♡ Nip Cushion Coverage
- ♡ Removable Padding
- ♡ Soft Stretch Fabric
- ♡ Matching-Set Style
The Bra That Makes the Set
The open back leaves the shoulder blades visible through movement, while the square neckline creates a clear, graphic upper-body line from the front.
Pair it with matching contrast leggings, shorts or a Twirl Skort for Pilates, barre and commercial dance. Add the Call Me Baby Ringer Tee during warm-up, then remove the layer when you are ready to show the crossed-back detail.
Dance World Fit Tip: The shoulder straps are fixed rather than adjustable, making torso length and shoulder width especially important. They feel secure when the proportions suit, but may sit longer or wider on shorter torsos and narrower shoulders.
Why We Recommend It: A beautifully defined studio bra that combines practical coverage and flexible support with one of POPFLEX’s most striking contrast-back designs.
