### Chapter 13: Deductions for Lacing Space

1. You have decided which lacing adjustment to use in the new
corset. The corset does not reach entirely around the body, as a
portion of the body is covered only by lacer. This is called lacing
space. A deduction is made from the actual measurement around
the body to allow for this lacing space. This is called "spacing de- duction" and differs according to the lacing adjustment selected.
Rules for spacing deductions and lacing spate
| 2. The spacing deduction for a back-laced corset is | Bust 3 inches waist 2 inches Hip 3 inches |
| When on the body the corset is spaced to this proportion | 3 2 3 Bust Waist Hip |
| 3. The spacing deduction for a front-laced corset is | Bust 2 inches waist 2 inches Hip 1 inch |
| when on the body the corset is spaced to this proportion | 3 2 3 Bust Waist Hip |
| 4. The spacing deduction for a combined front and back-laced corset is | Bust 3 inches Waist 3 inches Hip 3 inches |
| When on the body the corset is spaced to this proportion, divided between front and back | Front Back Bust Waist Hip |
5. While the spacing deduction is 3 inches from the hip meas- urement, the lacing space at the hip shows only 2 inches. This
extra deduction allows greater compression over the hip by drawing
the corset together an extra inch in the back when the final adjust- ment is made. The extra com pression secured in this way is a
specific function of the combined front and back-laced corset.
| 6. The spacing deduction for a front and par- tial back-laced corset is | Bust 2 inches waist 2 inches Hip 3 inches |
| When an the body the corset is spaced to this proportion, divided between front. and back | Front Back Bust Waist Hip |
7. While the spacing deduction is 3 inches from the hip meas- urement, the lacing space at the hip shows only 2 inches. This extra
deduction allows greater compression over the hip by drawing the
corset together an extra inch in the back when the final adjustment
is made. The extra compression secured in this way is a specific
function of the front and partial back-laced corset.
| 8. The spacing deduction far a back and partial front-laced corset is | Bust 3 inches Waist 2 inches Hip 5 inches |
| | Front | Back |
| When on the body the corset is spaced to this proportion, divided between front and back | Front Groin Front | 3 2 3 Bust Waist Hip |
9. After the spacing deduction has been made from the client's
actual body measurements you know exactly haw many inches are
required in the corset to cover the body at the bust, waist and hip,
and to allow for the lacing space. The number of inches at the
waist represents the waist size of the corset. To determine which
corset will give you the exact number of inches at bust and hip,
find the corset development the client requires.
 10. TO DETERMINE BUST DEVELOPMENT OF CORSET.
With the spacing deduction made, subtract the waist size from the
bust size. The difference is the bust development needed in the
corset. [Exception. If the client has a condition of scant bust, her
bust measurement after spacing deduction is made, must be in- creased. See Sec. 14, par. 6.]
 11. TO DETERMINE HIP DEVELOPMENT OF CORSET.
With the spacing deduction made, subtract the waist size from the
hip size. The difference is the hip development needed in the corset,
provided you have secured a good foundation over which you have
taken a tight hip measurement and the figure is not abnormal,
When the hip measurement has been taken under these conditions,
the hip size of the corset must always be exactly the same as the
client's hip measurement, less spacing deduction.
 12. To show how to make spacing deductions to determine waist
size and to find corset development from the client's actual body
measurements, let us assume the following:
| Bust Waist Hip | 40 28 39 |
13. When back lacing adjustment has been decided upon make
spacing deductions as follows:
| Bust Waist Hip | 40 — 3 == 37, bust size required in corset 28 — 2 == 26, waist size required in corset 39 — 3 == 36, hip size required in corset. |
14. To find corset development, subtract the measurements se- cured as a result of making spacing deductions, as follows:
| Bust 37  Waist 26  -- Bust Dev. 11 | Hip 36  Waist 26  -- Hip Dev. 10 | Written thus: Dev. 11:10. |
15. Proceed in the same manner with other lacing adjustments, making spacing deductions according to rules given in this section.
To determine waist size when the client's hip development,
less spacing deduction, is greater than the hip develop- ment of the standard corset under consideration
16. With the spacing deduction from the client's actual hip
measurement made, subtract the hip development of the corset you
are considering from the remainder. This will give you the waist
size that you must use in that standard corset. [Note: The use of
this method is modified by flesh conditions. See Sec. 14, Par. 14.]
 17. To show you haw to make spacing deductions and to deter- mine waist size when changing the proportions of an irregular
figure, with soft flesh, let us assume the following actual body meas- urements:
| Bust Waist Hip | 40 28 43 |
18. When back lacing adjustment has been decided upon, make
spacing deductions as follows:
| Bust Waist Hip | 40 —3 = 37 28 —2 = 26 43 —3 = 40 |
19. To find corset development, subtract the measurements se- cured as a result of making spacing deductions, as follows:
| Bust 37 Waist 26 — Bust Dev. 11 | Hip 40 Waist 26 —  Hip Dev. 14 | Written thus: Dev. 11:14. |
20. This development shows irregular proportions, so it would
be well to change them. In this case let us assume that the hip de
velopment is to be reduced 2 inches. To do this let us select a cor- set with a 12 inch hip development instead of 14. The hip measure- ment was taken tightly so the client's hip size cannot be made any
smaller. To find the waist size that will give you 40 inches of ma- terial around the hip (of this corset with a 12 inch hip develop- ment), subtract as follows:
* 40 Hip measurement less spacing deduction
* 12 Corset hip development
* 28 waist size required in standard corset.
21. This corset with a 28 inch waist size and 12 inch hip devel- opment produces straighter lines and so reduces the amount of
curve over the hips. The soft flesh is re-distributed upward by the
straighter lines of the new corset. This re-distribution of flesh fills
out the waist and bust of the corset and in this way changes her
figure lines.
 22. When this corset, size 28, is adjusted correctly with a 2 inch
lacing space at the waist, it makes the client's waist measurement
30 inches instead of 28 inches. This increased waist size and de- creased hip development changes the client's irregular proportions
nearer to normal.

are treated on page 90 of the 1916 catalogue.]
