How to Measure Your Bra Size
Use a soft tape measure and follow this quick bra fitting method:
- Band Size: Wrap the tape around your ribcage, under your bust. Round to the nearest cm.
- Bust Size: Measure around the fullest part of your bust. Make sure the tape sits flat.
- Subtract band from bust to find your cup size. Every 2 cm difference roughly equals one cup size increase.

Understanding Sister Sizes
If size 16K feels slightly off, consider trying sister sizes such as 14KK or 18JJ. These allow you to shift band or cup without changing overall fit. An expert bra-fitting service can guide you further, including virtual bra fitting services for convenience.
