How to measure your bra size
You’ll need a flexible tape measure. It’s also best to wear a bra that doesn’t change your shape — no padding or compression. You can also just skip the bra.
Measure around your rib cage where the bottom band would sit. The tape measure should feel quite snug. If you get a fraction, round down to the nearest inch. Using , find your corresponding band size based on your measurement.
Measure around the fullest part of your boobs — which may not be the center — and round up to the nearest inch. Then subtract your rib cage measurement. The difference in inches is your suggested cup size. If you get a fraction, round up to the larger size.
Four common fit myths
There’s a lot of advice out there about bras, but not all of it is good. Thanks to biomechanical testing with our partners at the University of Portsmouth and almost a thousand runner interviews, here are four common fit myths we debunked.
Myth #1: Support preference for running varies a lot
Surprisingly, our lab testing found that the amount of support women wanted for running fell within a fairly narrow range — even across a wide range of sizes. So we decided to make sure all our bras featured support within that specific range.
Myth #2: Your exact measurements dictate your bra size
Although measurements provide a great starting point, you might feel most comfortable in a slightly different size. It all depends on preference. Start with measuring, but try on a size up or down if it doesn’t feel right.
Myth #3: It doesn’t matter if I wear an unsupportive bra
Research has shown that the lack of support can actually slow you down: women can lose up to 4cm of stride length due to poorly controlled breast movement. Over the length of a marathon, that’s an entire extra mile. No thanks, we’ll take a better bra!
Myth #4: Wearing two sports bras offers better support
We wish all women would read this: if you are wearing a bra that fits properly and is specifically designed for running, you should never have to double up. It’s good to have a few different bras to rotate through the week, but the days of layering bras are long gone.
YOU’RE NOT ALONE
How we solved six common bra issues.
Skip the on/off struggle
Changing into your run bra should be easy. If pullover bras don’t work for you, try styles with adjustable back closures, or even zip-front designs.
Stop straps from chafing
Chafing is the worst. Try adjustable straps to fine-tune the fit, or free-cut finishing which practically eliminates edges on straps.
No more nipping out
Stay confident in your coverage with styles that feature built-in molded cups or removable cups.
Smooth out pesky seams
Bras with nearly seamless finishing or bonded finishing — a fancy way of saying seams are adhered with heat instead of stitched — help eliminate seam-on-skin irritation.
