Step 1/ Measure Band

Wrap a measuring tape around your back, pulling it under your arms and just above the bust. Take note of this measurement. Size Tip: round down if you get an odd number.

Step 2/ Measure Bust

Wrap the measuring tape around your back, pulling it under your arms to the fullest part of your bust. Ensure the tape is not pressing in and is parallel to the floor. Take note of this measurement. Size Tip: if the number falls on the half-inch (1.3cm), round up.

Step 3/ Find Cup Size

Take the difference between your band and bust measurements. The difference will indicate your cup size.

1" (2.5cm)=A cup
2" (5cm)=B cup
3" (7.5cm)=C cup
4" (10cm)=D cup
5" (12.5cm)=DD cup
