Make sure your student is standing straight, looking forward and has a natural posture. Their feet should be directly under their hips with their feet parallel but not touching.
For the most accurate measurements ask your student to wear a leotard as this will ensure the most accurate measurements.
Ensure that the student breathes in and out naturally to avoid the tummy sucking in and assure a comfortable fit.
Before you start taking measurements ensure that the flexible measuring tape is lying flat. When taking measurements make sure the measuring tape isn't too tight or too slack.
The inseam should be where the leotard leg line meets the tights or the top of the leg.
Measuring girth is the most important measurement. If a student is in between sizes, allow girth to be the guiding measurement to make your judgement.
