Fitting Tips

Good Fit/Bad Fit

Our Sports Bra Experts are here to help you understand when your sports bra is fitting properly... and when it isn't!


Your sports bra needs to fit well to ensure you can exercise comfortably and confidently. A badly fitting sports bra can lead to chafing, too much bounce, back and neck pain, and a lack of confidence during exercise.


Put on your sports bra, watch this video with a mirror handy, and let's evaluate the fit! We discuss the common pitfalls, the three key areas of support, and how you can fix the fit.

Making the Right Adjustments

For a quick-look written guide, see our Band and Cup adjustments below. Or, if you want a more detailed helping hand, then take a look at our Got Brablems? Survey results and our recommended top tips!

The Band

The band of your sports bra should be firm fitting and lie straight across your back on the loosest hook and eye fastening.

If the band is riding up at the back, or you suffer from straps digging in, then go down a band size (remember: if you do this, go up a cup size as well).

If the band is too tight, difficult to fasten or there is excess skin hanging out of the band, then you should go up a band size (remember: if you do this, go down a cup size).

The Cups

The cups should encase all of your breast tissue, and your sports bra should sit flush against your skin with a smooth transition from sports bra to chest.

If the cups are gaping, or you are experiencing chafing under the armpits, then the cup size is too big and you should go down a size.

If there is spillage of breast tissue out of the sports bra (from any direction!) or the bra sits away from the breastbone, then the cups are too small. Fix this by going up a cup size.
