Sports Bra Fitting Tips

The Band

The band of your sport bra should be a firm fit in a straight line across your back.  It needs to be a snug fit as this is where most of the support comes from.  If the band rides up your back, go down a band size (you may need to also increase a cup size too).  It is important to note that sports bra’s will feel firmer around the band compared to your everyday bras.  Most sports bras have less stretch in their band fabric for greater support than everyday bras, this results in a firmer fitting band.

If the band is too tight or there is excess skin hanging out of the band, go up a band size (you may need to also go down a cup size).  The sides of you bra should sit in a comfortable position.  If they’re too high under your arms they may rub and cause discomfort.

The Cups

Sports bra cups should sit flush against your skin and encase all of your breast tissue.  For a perfect fit your breast should be fully contained within the cup.  If the cups are gaping the cup size is too big.  If there is spillage of breast tissue out of the sports bra or it sits away from your breast bone, the cups may be too small.

When putting on your sports bra its best to lean forward and smooth the breast tissue into the cup.  Then grasp the front of the bra and jiggle slightly to settle everything into place.  An overly tight shoulder strap will also pull your cup up causing unnecessary spillage at the top of the cup.  Most of the bra support comes from the band, not the straps, so don’t pull them too tight.


It is commonly believed that underwire is essential for a more supportive bra; however research shows that underwire can give a great shape, but does not provide additional support.

Underwire should lie flat against your body and go around the contour of the breast.  If the wire is sitting high under your arms, or sitting on your breast tissue, rather than around your breast, then you are wearing an incorrect size or style.


Straps are at their perfect length when the breast feels supported in its natural position.  Adjust your straps so they are not digging in or sliding off your shoulders.  New bras often have their straps pulled tight, make sure you loosen these before trying on a new bra.  The majority of the sports bra support comes from the band, not the straps.  It is a misconception that the straps need to be pulled tight.  Too tight straps can effect the overall fit and comfort of your sports bra.

Breast Changes

Hormones, Ageing, Weight Fluctuations, Breastfeeding, Pregnancy all affect your breast shape.  Every time you go through one of these, you’ll most likely need a new sports bra.

We recommend you check your bra size every 6 months.

If your size fluctuates during the month, which is common, it is best to buy a larger cup size for that particular time of the month.  This ensures you have a supportive and comfortable bra at all times, especially when your breasts may be feeling more tender.
