How To Measure
Follow these steps for your perfect fit
1. Get a measuring tape
You can do this on your own or get a friend to help. Wear a non-padded, wired bra for best results. Always
relax and make sure your arms are by your side.
2. Find your band size
Align the tape around your body at ribcage level, directly under the bust, keeping the tape parallel to the
floor. Tape should feel snug but not tight around the body. Record your measurement.
Find your band size according to the measure chart.

3. Find your cup size
Wrap the measuring tape around your body at the fullest part of your bust, ensuring the tape is parallel to
the floor. The tape should fit comfortably around your body. Take note of this measurement.
Then, subtract your band size from your bust size to determine your cup size.
* For instance, if your bust measures 36 inches and your band size is 32 inches, the difference is 4
inches, indicating a cup size of D.
