Start by tying a string around your waist, keep this in place while you are measuring to act as a reference point.

1 Bust measure around the fullest part of the bust
2 Underbust measure around the chest underneath the bust
3 Waist measure around the narrowest part of the waist
4 High Hip measure around the body four inches below the the natural waist
5 Hip measure around the fullest part of the hip
6 Bust to Underbust measure the distance between the full bust and where you took the under bust measurement
7 Underbust to Waist measure the distance between where you took the under bust measurement and the natural waist
8 Waist to Bottom of Corset measure from the natural waist to where you want the bottom of your corset (remember you don't want the corset to dig into your legs when you sit down)
9 Finished corset length measure centre front from the top to bottom (see note 8) of where you want the corset to start and finish.

For some over bust styles the measurement around the body above the bust (where there is a line above line 1 in the drawing) and the distance between that and the full bust (1) will be required.

If any additional measurements are needed you will be advised accordingly.
