Sportswear
A sports bra only does its job if it actually fits, and for a fuller bust that means proper cup sizing rather than a stretchy small, medium or large. Our sports bras are sized the way our everyday bras are, by band and cup, so sizes like 10G, 12G, 12F and 14F are genuinely here rather than lumped into one broad size. Whether you run, lift, do yoga or walk the dog, the right underwire sports bra or wire-free style holds you firmly and comfortably, protecting your breast tissue from the bounce that causes soreness. This is serious, cup-sized sports support for real bodies, made to keep up with whatever you do.
Why Cup-Sized Sports Bras Matter
Standard small-to-large sports bras simply cannot support a fuller bust well. Without a defined cup and band, they flatten and compress rather than genuinely holding you, which is uncomfortable and does little to protect against bounce. Our range is cup-sized from a 6 to a 28 back and up to a K cup, so you get the same accurate fit in activewear that you would in a good everyday bra.
That accuracy matters for more than comfort. During exercise, unsupported breast tissue moves a lot, and repeated strain on the ligaments that support the bust can lead to soreness now and sagging over time. A properly fitted sports bra limits that movement, from specialist labels like Panache Sport, Elomi, Freya Active, Sculptresse, Glamorise and Primadonna Sport.
Underwire, Wire-Free or Moulded?
There are three main types, and the best one depends on how much hold you want. The wired sports bras linked above give the firmest, encapsulated support, cupping each breast separately, which suits a fuller bust and higher-impact exercise. Wire-free sports bras offer soft, flexible comfort with no wire, ideal for lower-impact days and all-day wear. Moulded sports bras use shaped cups for smooth, structured support under clothing without a visible wire.
Choosing for Your Workout and Value
Match the support to the activity. High-impact exercise like running or HIIT calls for the firmest wired or moulded styles, general gym and cardio sit in the middle, and yoga, pilates or walking are comfortable in softer wire-free bras. A well-made, cup-sized sports bra is an investment that holds its shape and support far longer than a cheap generic one, so it works out better value over time.

Frequently Asked Questions
Do you have sports bras in cup sizes like 12G or 14F? Yes. Our sports bras are cup-sized rather than sold as small, medium or large, spanning a 6 to 28 back and up to a K cup, so fuller-bust sizes like 10G, 12G, 12F and 14F are genuinely stocked.
What is the difference between underwire, wire-free and moulded sports bras? Underwire (wired) gives the firmest encapsulated hold, wire-free offers soft flexible comfort with no wire, and moulded uses shaped cups for smooth, structured support. The right one depends on the support and feel you want.
Which sports bra is best for high-impact exercise? For running, HIIT or a fuller bust, a firm wired or moulded style gives the most control over movement. Lower-impact activities like yoga and walking are comfortable in a softer wire-free bra.
Do you have more affordable options? Quality cup-sized sports bras last far longer than cheap generic ones, so they are better value over time. For lower prices, check our sale sportswear, and remember shipping is free Australia-wide over $150.
