Take your measurements
To find your correct size, use a tape measure and take these measurements. Stand with your back straight in front of a mirror, to make sure that you measure correctly and that the tape measure is kept level.
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.
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.
The hip should be measured around its fullest part (about 8 inch. below your waist).
This is the measurement from your ankle to your groin, when you stand with your legs straight. If possible, ask a friend to help you. This can also be measured on a pair of pants with the proper length.
