* All measurements are guides only. From time to time some people might find that their perfect size does not line up with the size chart data.
Bust:
Wrap measuring tape around the fullest part of the bust, ensuring the measuring tape is sitting straight across the back when taking the measurements. Once the measuring tape is in position keep the arms relaxed and by the side.
Under Bust:
Wrap measuring tape around the ribcage, just below the bust, ensuring the measuring tape is sitting straight across the back when taking the measurements. Once the measuring tape is in a position keep the arms relaxed and by the side.
Hot Tips 🔥
- The measuring tape should fit closely around the body without squeezing in any way.
- If your bust and under bust measurements fall in different sizes, we recommend following the size of your under bust measurement.

"Such a great medium support bra. Used it in my recent marathon and it felt so comfortable yet supportive. Didn’t cause chaffing. Plus the colour is so cute! Want it in every colour!"
"The bra is a great fit and very supportive. My only frustration is that every time I wash it, the cup inserts come out in the washing machine. They are quite difficult and time-consuming to put back in, which adds an extra 4–5 minutes to my morning routine. Considering the price, I expected the inserts to stay in place better. Other than that, it's a great bra and I am happy with the fit and support."
"Absolutely love this sports bra! The sizing is spot on. I usually sit somewhere between a small and a medium, but I went with a small because I prefer a tighter fit for running, and it fits perfectly without feeling restrictive. The cut is really flattering, the colour is to die for, and the fabric is incredibly soft and breathable. It stays comfortable throughout my runs and provides great support. Definitely recommend!"
"Finally found a bra that I can wear for all types of workouts, in particular running. Great quality and design. Gives me the support I need when doing my runs. Super smooth material, a make that feels like it will go the distance and last a long time. My order came super fast, as always super impressed with the service."
"Super comfortable, excellent support, no chafing, and stayed in place the whole time. The soft fabric and pretty color are bonuses. Great for running or workouts. Highly recommend! 💪"
"Bra is really secure yet comfortable. Easy to put on, soft fabric and easy clasps. Really enjoying training with it and is becoming my go to for high intensity/high bounce activities."
"Cup area quite small - squished and barely covering what’s needed but fits perfectly around everywhere else - needs more fabric unless meant to be super low cut! Beautifully soft fabric and lovely to wear though!"
"This bra is so comfortable, thick, good quality, sweat absorbent and pretty colour. I love it. A new favorite for sure. Definitely would like buy again."
"The only crop I will wear running. The girls are supported and it doesn’t feel like you are wearing anything. Only negative is that the removable padding moves around and is visible through the crop."
"Race day sports bra is my new ABSOLUTE FAV!! Great support, soo comfortable and love the back that it has clips to make it tighter etc 🧡🧡 more colours here we come x"
