When I need measurements, these are the charts I usually use. I usually don’t need all the measurements on any one chart, and usually also ask for base of next to the floor. Measurements can be in inches or centimeters.
When measurements are taken, please be very careful. Providing incorrect measurements can result in something that can’t be altered well. Don’t provide your dream-measurements, no matter what. Incorrect measurements, whether by accident or intentionally (a lot of brides intend to lose weight, but don’t succeed, and I’m not responsible for this) happen with some frequency. A great-fitting ensemble requires accurate measurements.
