Use a tape measure to measure yourself, holding the tape securely around the 4 key points.
To achieve an accurate measurement we recommend you take these measurements whilst wearing minimal clothing.
- BUST Measure over the fullest area of your bust & straight around your back.
- UNDERBUST Measure directly under your bust & straight around your back.
- HIP Measure at the fullest part of your hip ensuring the tape is straight.
- TORSO Measure top of the shoulder, down between legs and back up to the top of shoulder.
Refer to the table above to confirm the correct size.
If you don't have a tape measure home you can print out this one for your convenience: Download Slix Rule in Metre and Inch
