Here's how to take the measurements correctly. Wear underwear as other clothes may distort your measurements.

Chest circumference: Place the tape measure horizontally around the chest passing under the armpits, keep the arms down

Bust circumference: place the tape measure horizontally around the chest passing over the most protruding point of the breast

Waist circumference: Place the tape measure horizontally around the narrowest point of the waist

Pelvis circumference: Place the tape measure horizontally around the widest point of the pelvis

Breast position: measure vertically from the shoulder point to the most protruding point of the breast

Skirt Length: Measure from the waist to the length you want. If you will wear shoes with heels remember to take the measurement wearing them.
