In a few years pants will again be worn smaller at the knee, and Dia. XIX
must be reduced at the knee and at the thigh. It is hard to tell what the
bottoms will be then, but for all that the center of foot and heel is
here for a guide. Time will show if pants will then be made with large
spring bottoms or whether they will be made again as they were a few
years ago, hardly large enough for the leg to pass through. But I will
say this. Dia. XIX will fit at the seat and upward for any style. At the
fork it may be reduced one seam on the forepart only, and at the side of
thigh it may be reduced one seam on each back and on each front, for a
close fit.
At the side of the knee the angle of 10 deg. may be hollowed out ⅝ to ¾
on each back and on each front, or so much as the inward curve of side
of the knee will warrant. At the inside of the knee allow ¼ to ⅜ on the
double to the angle of 10 deg., all of which will produce a knee of about
18 inches made up, and that will be pretty close for a seat of 38. Again,
if size 38 is reproduced for a size 35, the knee will be about 18½ inches
made up, and if from this is taken away ½ inch on each forepart and on
each back at the side of the knee to represent the hollow of the leg
there, and which is not shown in the present style, the knee will make up
17½ inches which again is a fair width for a narrow leg for size 35.
Another good way to produce a close fitting knee is this: From the
center line of the angle of 10 deg. measure both ways and give on the
double inseam ¾ inches more than on the double outside, and this rule
will hold good on all forms, because the center of the angle of 10
degrees is the center for the pants leg, but the inside of the leg is
straight while the outside is hollowed out about ¾ inches, and that
hollow must be imitated in order to make a close fit of the pants.
