Size & Fit Advice

The POPFLEX Be Flexible Onesie uses the brand’s highly stretchy Seamless Flex sizing rather than conventional single-size activewear.

If you fall between two Flex options, choose the smaller suitable size for a more sculpted, compressive fit or the larger size for a softer, more comfortable hold.

Bust, hip and torso length should all be considered. Because the shoulder straps are fixed, sizing up creates more room through the body but does not independently adjust the neckline or strap position.

Dancers with a longer torso or fuller bust may find that the sweetheart neckline sits lower. As a useful secondary check, measure your girth in one continuous loop from the centre of one shoulder, through the crotch and back to the same shoulder.

When trying the onesie, lift both arms and perform a forward fold. The neckline should remain secure without pulling uncomfortably at the shoulders or crotch.

Description

One Beautifully Unbroken Dancer Line

Clean, sculpted and made to move, the POPFLEX Be Flexible Onesie creates one uninterrupted line from its sweetheart neckline to its full-length legs.

The polished Black finish feels naturally at home in dance, while POPFLEX’s seamless stretch, light bust support and carefully placed contouring make it equally suited to Pilates and studio conditioning.


POPFLEX Be Flexible Onesie – Design & Support

The sweetheart neckline is balanced by an ultra-low scoop back, creating a distinctly dancer-led silhouette. The shoulder straps are fixed rather than adjustable, keeping the upper line clean while making torso length an important part of the fit.

Ribbed panels create additional definition through the waist, while a heart-shaped back seam follows and shapes the seat. At the front, the absence of a centre seam creates a smoother line, supported by a moisture-absorbing cotton gusset.

An internal shelf bra provides light support, with space to add your own removable pads if preferred. Pads are not supplied with the catsuit.


The POPFLEX Why

One-Piece Studio Line

The fitted full-length shape creates a clean, uninterrupted silhouette without a waistband or separate layers.

No Front Seam

A smooth front construction helps reduce unwanted definition through the centre of the catsuit.

Light Support Built In

An internal shelf bra provides gentle support and can accommodate your own removable pads.

Purposeful Contouring

Ribbed waist panels and a heart-shaped back seam add definition while preserving complete stretch.

What POPFLEX Customers Notice

The stretch makes the fit surprisingly flexible. Choose the smaller suitable Flex size for more sculpting or the larger option for a softer, more comfortable hold.

Torso and bust proportions matter. The fixed straps work beautifully when the catsuit matches your vertical body length, but a longer torso or fuller bust may pull the sweetheart neckline lower and reduce security through forward folds and larger movement.


Made for Movement You Can See

The close seamless fit allows teachers to see alignment clearly through Pilates, barre, conditioning and contemporary movement. With no separate waistband or loose fabric, the catsuit remains smooth through floor work, extensions and changes of level.

The shelf bra is intended for light support. Dancers with fuller busts or those planning jumps and higher-impact choreography should test the neckline through a forward fold and raised-arm movement before class.
