POPFLEX recommends using your body measurements rather than relying on your everyday clothing size. Compare your bust, waist and hip measurements with the chart below and always check the individual product's fit notes, as different silhouettes can feel more sculpting, relaxed or adjustable.
POPFLEX Women's Size Chart
Use your bust, waist and hip measurements to find your recommended POPFLEX size.
| Measurement | XS | S | M | L | XL |
|---|---|---|---|---|---|
| Bust | 79–84 cm 31–33" | 84–89 cm 33–35" | 89–94 cm 35–37" | 94–102 cm 37–40" | 102–109 cm 40–43" |
| Waist | 61–66 cm 24–26" | 66–71 cm 26–28" | 71–79 cm 28–31" | 79–86 cm 31–34" | 86–96 cm 34–38" |
| Hips | 86–91 cm 34–36" | 91–97 cm 36–38" | 97–102 cm 38–40" | 102–109 cm 40–43" | 109–122 cm 43–47" |
POPFLEX designs can vary from highly sculpting leggings and fitted tops to adjustable-waist skorts and more relaxed layers. If your measurements fall across two sizes, prioritise the measurement most relevant to the garment — waist and hips for bottoms, and bust for fitted tops or bras — then check the product-specific fit advice.
How to Measure for POPFLEX
Measure over underwear or close-fitting clothing using a flexible tape measure. Stand naturally and keep the tape comfortably against the body without pulling it tight.

Bust
Tops & BrasMeasure around the fullest part of the bust, passing the tape underneath the arms and keeping it straight and level around the body.
Keep the tape comfortably close without compressing the bust.
Waist
Bottoms & SkortsMeasure around your natural waist, usually the narrowest part of the torso. Keep the tape level and comfortably against the body without pulling it tight.
Hips
Measure around the fullest part of the hips and seat while standing naturally. Keep the tape level all the way around the body.
Height
Stand straight without shoes, with feet flat on the floor, and measure from the floor to the top of the head.
POPFLEX does not use height in its core XS–XL body-size chart, but it can be useful when comparing garment lengths and longer silhouettes.
Inside Leg
Measure from the top of the inner thigh down the inside of the leg to the ankle while standing straight.
This is a useful secondary measurement for leggings, trousers and full-length styles, but it is not part of POPFLEX's standard XS–XL body-size chart.
POPFLEX uses the same core bust, waist and hip measurements across much of its clothing range, but the feel of the garment can vary significantly depending on the design. Sculpting leggings and fitted tops may feel closer to the body, while adjustable-waist skorts, trousers and relaxed layers can offer more flexibility. Use this chart as your starting point and always follow any product-specific Dance World fit advice where provided.

Description
A Little Contrast, a Lot of Impact
The POPFLEX It Girl Bra uses crisp white trim to frame every important line, from the square neckline and shoulder straps to the supportive underbust band.
Clean and minimal from the front, intricately crossed at the back, it brings a polished fashion-sport mood to Pilates, dance and complete studio sets.
POPFLEX It Girl Bra – Design & Support
A straight square neckline creates a clean, open frame across the collarbones, with contrast binding clearly defining the shape. Wide fixed straps continue over the shoulders before meeting an open back with layered criss-cross detailing.
A contrast underbust band completes the graphic outline and provides a close, secure base. Inside, POPFLEX’s Nip Cushion layer adds discreet coverage, while removable pads allow you to adjust the finished shape.
The soft polyester-and-spandex fabric stretches comfortably around the body, providing low-to-medium-impact support. Dance World stocks Cosmic Navy with White and Black with White.
The POPFLEX Why
Framed Square Neckline
White binding clearly defines the open neckline and creates a clean, lifted-looking upper line.
Sculptural Criss-Cross Back
Layered back straps turn a practical support feature into the bra’s most striking detail.
Nip Cushion Coverage
An additional internal layer provides discreet coverage beneath the smooth outer fabric.
Removable Padding
Internal pads can be retained for more shape or removed for a softer, more natural profile.
POPFLEX It Girl Bra Wear Profile
The Dance World Wear Profile highlights the fit, feel and practical characteristics of each POPFLEX design. This profile reflects the It Girl Bra specifically.
What POPFLEX Customers Notice
The contrast looks exceptionally clean. Customers particularly like the sharp Navy-and-White combination and the way the trim turns coordinating leggings or shorts into a complete outfit.
The neckline creates visible definition rather than flattening the bust. This makes the design especially popular with smaller busts, while the removable pads provide additional shape if desired.
The fixed straps make body proportions important. They can feel secure and flattering when the torso length is right, but may sit long or wide on shorter torsos and narrower shoulders.
The Bra That Makes the Set
The It Girl Bra works particularly well for dance because the open back leaves the shoulder blades visible, while the square front creates a clear, graphic upper-body line.
Pair it with matching contrast leggings, shorts or a Twirl Skort for Pilates, barre and commercial dance. Add the Call Me Baby Ringer Tee for warm-up, then remove the layer once the body is ready to move.
Dance World Notes & Verdict
- The straps are not adjustable. Bust size, shoulder width and torso length all influence how securely the upper line sits.
- The Nip Cushion layer remains when the pads are removed. Removing the pads changes the shape, but does not leave only a single layer of outer fabric.
- This is not a high-impact running bra. Its strongest activities are Pilates, barre, dance, strength work and everyday movement.
✦ Contrast Collection Standout
The It Girl Bra proves that contrast works best when it follows the construction. The white trim defines the neckline, supports the underbust and transforms the back straps into a genuine design feature, creating a bra that looks as considered alone as it does within a matching set.
