Max Support vs. Eco Jersey
The Max Support styles run more snug and compressive compared to the Eco Jersey. Max Support is a nylon-spandex fabric based on a double knit weave while the Eco Jersey is a medium weight polyester-spandex knit.  


Find your Freedom Bra size below based on your band and cup (based on US bra sizes). For example, 34A is a size Small. For the best fit, use the applicable size chart using your underbust and bust measurements. Example: 34A bra wearer can have an underbust measurement of 30" - 32". 

Eco Jersey Bra Size Chart


Because bra band/cup sizes can vary by brand and style, we prefer the measuring tape method.

Wrap the measuring tape around your body (circumference)


  • Bust: Measure around the fullest part of your bust.
  • Underbust: Measure around your bust where your breasts meet your rib cage.


  • Waist: Measure around natural waistline (about 2 inches above belly button).
  • Hips: Measure around the fullest part of your hips.

Below is a general cross-reference to US bra sizes (average bust & underbust in inches). US bra band sizes go across horizontally with corresponding underbust (rib cage). Cup sizes are listed vertically with corresponding bust size (fullest part of the bust). *If you're viewing from your phone, rotate phone to view wide screen to see full chart.

When it comes to fit, choosing a smaller size will increase compression while a larger size will provide more bust coverage.

What if you fall between sizes?
By design, our wireless bras are flexible. If your size falls between two sizes, consider your breast shape for volume. Do you have full volume breasts? Then choose the bigger size. Do you have less volume or shallow breasts, or a more petite frame? Then consider going with the smaller size.

Our tops are designed with built-in bra support. We recommend using your dress size and reference bra size to determine best fit. For example, if you wear an XL in the Freedom Bra, we recommend ordering at least a size XL in the Top (i.e. Unity Top, Freedom Top).

Our hi-rise bottoms are designed to comfortably support your tummy, waist, and lower back.
