Hi, the bust measurment equals PTP x 2
which means, this design bust 36-40 inch, equals PTP 18-20''
the waist also the same, we provide the full around waist measurement, no the half waist. Our measurement like 29-32'' (inch), which may consider as 14.5-16''(inch) used by other seller which only provide half waist measurement.
All measurement based on actual piece, measured by hand. due to manual measurement a difference of 0.5'-1' may not be considered defects.
