Measure A to B = 25 cms = Montant
O = ½ AB then draw BC line and B is a right angle.
Measure BC = ⅓ of Front Hip line and DE = BC + 1 cm
Draw arc line OC and CE.
Culotte BACK Pattern
At zipper, entend bottom long skirt line to P = 1 cms
Measure F to G = 25 cms (montant)
FI = ⅓ FG; then draw GH line and G is a right angle.
Measure GH = ⅓ of Back Hip line.
Draw arc line IH = PQ = GH + 1 cm then draw HG line.
Fit Culotte Pattern
Measure AOC + FIH = Measurement + 10 cms
If it's shortter, measure OC and IH down until fit.
After that modify culotte pattern as the same as skirt pattern
