Fitting Tips
Finding the Perfect Fit
Our Sports Bra Experts are here to help you and your child spot when a sports bra fits just right… and when it doesn’t!
A good fit helps them move freely, feel confident, and focus on their sport — not their bra.
A bad fit can cause discomfort like chafing, too much bounce, back or neck pain, and make them want to avoid exercise altogether.
Pop on the sports bra, grab a mirror, and press play on our short video. We’ll guide you through what to look for, the three key areas of support, and how to make simple tweaks for the perfect fit.
Making the Right Adjustments
It can be tricky to tell what’s “right” and what’s “not quite there” when it comes to fit — but once you know what to look for, it’s much simpler!
Here’s a quick guide to help you make those small but important adjustments.
1. The Band – Where Most of the Support Comes From
About 80% of support in a sports bra comes from the band, so that’s the best place to start.
- The band should feel firm but comfortable — try taking a few deep breaths, like during warm-up.
- If it feels hard to breathe or digs in, it’s too tight. Try going up a band size.
- If it rides up your back or feels loose, the support won’t be there. Try going down a band size.
Your band should sit straight around your body, not slope upwards. You should be able to slide two fingers comfortably under it all the way around.
A new sports bra should fit perfectly on the loosest set of hooks. As it stretches with wear, you can move to the next set every few months. Sports bras work hard — so expect to replace them about once a year or sooner if size changes.
2. The Cups – Where Comfort Meets Confidence
If there’s spillage (tissue bulging out of the top, sides, or underneath) or the bra sits away from the chest, the cups are too small. Try going up a cup size.
If there’s gaping or wrinkling in the fabric, or rubbing under the arms, the cups are too big — go down a cup size.
The cups should encase all of the breast tissue with a smooth line from bra to skin.
Swoop & Scoop!
This is our top fitting tip:
Lean slightly forward, reach your opposite hand inside the cup, and gently scoop your breast upwards and towards the centre. Repeat on both sides. Sometimes, a quick swoop and scoop is all it takes to fix the fit!
3. The Straps – Fine-Tuning the Fit
Once the band and cups feel right, use the straps for small adjustments.
There should be 1–2 inches of stretch at the top of the shoulder. Straps that are too tight can dig in and cause red marks. Too loose, and you’ll lose that supportive feel.
If you find you’re always tightening the straps or they’re digging in by the end of the day, your band is probably too loose — try going down a band size.
Remember: Not all sports bras have adjustable straps. If you’re shopping for growing bodies, or just prefer more control, choose a style that lets you tweak the fit.
