Measure under your armpits, around your shoulder blades, and over the fullest part of your bust. Don’t pull the tape measure too hard. For fitting a bra, you also need the measurement just under your bust.
WAIST
Measure around your natural waistline. This is the narrow part of your waist, about an inch above your navel. Relax and breath out before you measure.
HIP
The hip should be measured around its fullest part (about 8 inch. below your waist).
