Edwardian era dates are 1901-1910, this book was published in 1919. The book states its references as 3 books by Amy J Reeve published in 1912. I think this is close enough and this is the draft instructions many online sewists use to make their own “Edwardian” combinations.

Original Draft Measurements
Waist to knee = 61cm
Waist = 61cm
Hip = 96cm
My Measurements
Waist to knee = 60cm
Waist = 61cm
Hip = 102cm
To Draft Drawers
Fold paper lengthwise.
AB = length to bend of knee
AC = (AB/2) – 6.4cm
AD = (waist/4) + 5cm
DE = waist/12
AF = (waist/4) + 1.3cm
FG =(waist/8)
(Draw curve AG using Haslam ruler placing front Curved arrow at point G.)
(Draw curve AE using Haslam ruler placing front arrow G at point G.)
CH = (waist/2) + 1.3cm
BI = 61cm (Original instructions say BI = Waist, if I draw BI as my larger waist it is impossible to complete line HK. Therefore I kept this as the original draft waist measurement of 61cm)
IJ = line of indefinite length at right angles to BI. HK = 19cm (use H as a pivot to swing line, K touching IJ).
GH is dotted line.
LH = 12.5cm
LM = 3.8cm (M at right angle to L).
EMH is curve for front. (Use Haslam Ruler to draw curve placing front curved arrow at point H)
HN = 10.2cm
NO = 10.2cm (O at right angles to N).
GOH equals curve for back. (Use Haslam Ruler to draw curve placing front corner 1 at point G, draw curve GO. Then place front B|C at point O – draw curve OH.)
BK is curve for lower edge of drawers. (Use waist curve AE to inform bottom curve using length AB to swing round)
AP = 7cm
CR = 15.3cm
PR is the grainline (drawn as __ . __ . __ . in diagram).
GS = 9cm
Inverted Pleat in Back
ST = Ruler at right angle to AG (draw as — — — — — in diagram).
This line ST is for fold of pleat which is laid to center back of drawers.
Habit Back
GU = 6.4cm
UO is curve for habit back. (Use Haslam Ruler to draw curve placing .)
Ruffle
BV = depth of ruffle minus seam.
KW = depth of ruffle minus seam.
VW is parallel to BK, line upon which pattern should be folded before cutting drawers from material, if a ruffle is to be used for trimming. (I don’t understand this instruction)
