You will need a tape measure to get the most accurate measurement.
Bust: To measure your bust, place the tape measure under your armpits and measure the fullest part of your bust.
Waist: Place the tape measure around your natural waist line, Do not tighten the tape measure around your waist. (this will result in an incorrect size).
Hip: Place the tape measure around the fullest part of your hip. NOTE (your hip is usually 8 inches below your waist line *this may vary.).
*Never assume your size and not measure.
* If you fall in between sizes, then the safe thing to do is always size up!
