Wear your usual undergarments.
Use a soft measuring tape.
Hold the tape measure straight, flat on your skin and snug, but not too tight.
Commit to either centimeters (cms) or inches (in)
Choosing measurements, always round up to the nearest half or whole number e.g. 26.5 or 27.
Measure twice for accuracy.
