AT-HOME SIZE GUIDE
Finding a bra that fits right is key to getting good support. Before we get started, make sure to wear a lightly lined bra (not a push-up or sports bra) to get as close to your natural fit as possible. You'll also need measuring tape.
STEP 1: MEASURE YOUR BAND
Wrap the measuring tape around your back where your chest band sits. Pull each side of measuring tape under your arms and around to the front, and meet just above bust. This is your band size.
STEP 2: MEASURE YOUR BUST
Wrap the measuring tape around your back at band level again, but this time bring it around to the front at the fullest part of your bust. Add a little slack, so that the two sides of the tape meet in a 90° angle (T-shape). If the number falls on the half inch, round up.
STEP 3: FIND YOUR CUP SIZE
Time for a little math (just a little, promise). Take the difference between your two original measurements (band—even if it was an odd number—and bust). The difference will indicate your cup size.
STEP 4: CONVERT YOUR SIZE
