stefano pilati for YSLFeatured:  Stefano Pilati for YVES SAINT LAURENT

Explore volume and proportion by challenging conventional principles of tailoring for your Autumn wardrobe. Here is a great example by Stefano Pilati for YVES SAINT LAURENT, a ‘zoot’ trouser balancing a fitted cropped top. The pattern draft is a bit more advanced for those daring to try pleated trousers yet it is an easy project to construct.

You will need:

  • Bottom-weight fashion fabric, 54” [137cm] wide **
  • ¼ yd. [0.25 m] of fusible interfacing, 45” [114cm] wide.
  • ⅓ yd. [0.30 m] of pocketing fabric, 45” [114 cm] wide
  • 1 zipper, 7” [18 cm] long.
  • 1 set of pant hook & bar
  • Kraft paper

** A minimum of 3 yards of fabric is required for pleated trousers – for an average sized person. If you’re taller than 6′ – you’ll need 3 1/2 yards of fabric.


Waist – measure around narrowest part of torso just above the navel.

Hip – measure around fullest part of seat, about 9” [23cm] below waistline.

Body Rise – measure vertically from waistline to top of chair seat, while seated.

Outseam – measure vertically from waist to heels.

Trouser Bottom Width – measure length of foot.


Easy Fit template for “baggy” trousers.

Front (Red)

Draw a long straight line down center of the paper and plot point 0 at the top end.

Square both ways from 0.

0-1 = body rise – waistband width + ⅜” [10mm]; square across.

0-2 = 9” [23cm] – waistband width; square across.

0-3 = outseam – waistband width; square across. (creaseline)

1-4 = half the measurement of 1-3 minus 2” [50mm]; square across.

1-5 = 1/12 of hip + ¾” [20mm]; square up to locate 6 and 7 at intersections.

6-8 = ¼ of hip + 1” [25mm].

5-9 = 1/16 of hip + ⅜” [10mm].

Join 10-6 with a straight line and 6-9 with a smooth curve, missing 5 by approx. 1 ⅜” [35mm].

10-11 = ¼ of waist + 2” [50mm].

3-12 = ½ of trouser bottom width – ¼” [6mm]; join 8-12 with a straight line. Mark point 13 on kneeline.

Draw in side seam; join 8-11 with a slight curve.

3-14 = ½ of trouser bottom width – ¼” [6mm].

4-15 = the distance of 4-13.

Draw inside leg seam; join 14-15 with a straight line; join 9-15 with a slight curve inwards ⅜” [10mm] as shown.

Back (Blue)

5-16 = ¼ of measurement 1-5; square up to locate 17 on hipline and 18 on the waistline.

15-29 = ⅜” [10mm].

Draw inside leg seam; join 28-29 with a straight line; join 29-24 with a curve inwards by ⅜” [10mm].


Most easy fitting trousers require extra ease in the back crotch line, especially pleated pants. Trace off back section of trouser template and add more ease. Begin by, cutting along the hipline and spread open a wedge as desired, approximately 1 ½” [40mm] wide at the back CB line. (The more rounded the behind, the greater the seat angle.) Re-draw the back seam curve as shown.

easy fitting pant adaptation

Style Adaptation

Pleated “zoot” trousers are full at the waistline and shaped in at the hem.

Trace round basic easy-fit trouser template onto additional paper.

Back Section *

Add additional ease in CB seam if necessary (see above).

Mark points (a) and (b) on hemline ¾” [20 mm] inward from leg seam.

Draw straight line from (a) to kneeline.

Draw in a bowed outseam (curve) from hipline tapering to (b).

Shape the bottom hemline with a slight curve outward ⅜” [10mm]. ***

Divide line 21-22 into 3 equal parts. At each point, draw in a waist suppression dart.      (2 in total).

Dart = 1 ⅛” wide x 4” long [30mm x 100mm].

Front Section *

Trace round front trouser template onto additional paper.

Cut across kneeline; then cut top section dividing along the crease (grainline). Spread open at waistline for desired amount of pleating and extend waistline at side seam to blend smoothly with outseam of leg.  (For instance, open 2” [50mm] at waist and extend 1 ⅜” [35mm] at side seam. With dart allowance this gives 4 ⅛” [10.5 cm] fullness).

Divide fullness into 3 equal pleats.

Design Note: More fullness can be added at the waistline by opening the grainline further at the waist and making deeper pleats.

Mark points (c) and (d) on hemline ¾” [20 mm] inward from leg seam.

Draw straight line from (d) to kneeline.

Draw in a bowed outseam (curve) from hipline tapering to (c).

Shape the bottom hemline with a straight line. ***

Grainline is parallel to creaseline.

For fly & fly facing *, trace off CF seam and waistline from 10.

Draw a parallel line 2” [50mm] from CF line and taper 1” [25cm] below zipper notch.

Grainline is parallel to CF line.

For waistband *, draw a long rectangle equal to the waist measurement X desired width.

Add a 2” [50mm] extension to one short end of pattern.

pocketMirror the final dimensions of the waistband along the foldline.

Grainline is parallel to foldline.

For sideseam pockets, make a pocket bag pattern *.

A-B = 9” [23 cm]; square across from A and B.

A-C = 6” [15 cm]; square down to locate D.

A-E =  6” [15 cm]; square across.

B-F = 1” [2.5 cm]; square up to G.

Draw in an arc with a compass from H to I as shown.

Fold paper on line C-D and trace off C-A-E-G-H-I-D as mirrored image. Open flat for bag pattern piece.

Grainline is parallel to foldline.

lay* Add seam allowances to all pattern pieces.

*** Add 1 ¼” [30mm] hem allowances to trouser bottoms.

These long and loose bottoms score high on the comfort index. The fabrics are fluid and the prints are fun, which means they are less for curling up on the sofa than for spending a weekend afternoon in style. Think silk, linen, rayon, or cotton…something lightweight and drapy. Balance them with a body-fitting top or stay faithful to the bedtime look with a big and beautiful sweater.

Featured: Blue-green silk pajama pants from Dries Van Noten

The cut and fabrication of these loungers is novice level and fits many shapes and sizes. It’s an easy “no-pattern” afternoon project.

You need:

  • 1 ½ yds. of fashion fabric, 44-45″ wide
  • Coordinating thread
  • 1 pkg. of 1″ wide waistband elastic or 60″ drawcord
  • Tailor’s chalk
  • Tape measure


No real pattern is required but if you wish to make several pants you can make a paper template.

Recommended to control the fullness at the gathered waist is elastic or a drawsting. The waist can accommodate 30″ to 52″ approximately.

For the cut, measure your finished pant length. (waist to heel). Add 1″ for cuff hem allowance and 1 ½ ” for waist casing to this measurement. Record it.

Straighten the cut edges of your fashion fabric and square across the width.

Measure along the selvedge the pant length measurement and square a line across the width with tailor’s chalk

Divide the section equally in half parallel to the selvedge with a chalk line. These are the left and right leg sections.

On each leg section, measure in approx. 2-4″ from the lines. This may vary based on how fitted a bottom cuff you want (must be able to get your foot through however). Then, measure along the length and find the midpoint. Chalk a notch. (X and O on diagram). Join Xs and Os to bottom points at hem with a straight edge using chalk.

Take this “midpoint” measurement and plot it along the waistline. Add 13″ for the rise. Square up on remaining fabric parallel to selvedge and mark with chalk. This is the gusset section.

Divide the gusset section in half by squaring across the fabric width.

Measure across top and bottom the distance equal to half the leg distance from waistline to X. Plot it and mark with chalk. Repeat but measure the dividing line from the opposite end. Join the notches with a straight edge. (see diagram).

Cut on the chalk lines. You will have a left leg side, a right leg side, and 2 pairs of gussets.


Finish raw edges with desired seam finish. (I used pinking shears).

With right sides together, pin and baste a gusset to each center portion of the legs. (Match Xs and Os). Stitch seam and press open.

With right sides together, fold each leg section in half lengthwise and pin and paste inseam from crotch to hem. Stitch inseam and press seam open.

Turn one leg section right side out and place it down the other leg section. Match up CF and CB at waist and align inseams. Pin and baste gussets together and stitch crotch seam. Press open. Turn pants right side out.

Turn under 1/2″ at waistline and press. Turn under 1″ all round and machine stitch down to create a casing. Open a slit in the front crotch seam at the waist to insert an elastic or drawcord. (make elastic equal to your waist measurement less 2″ if using).

Hem bottoms of legs using a 1″ hem allowance.

body proportionsThis pattern design method can be used to determine drafting measurements from a given figure height combined with girth measurements for the chest, waist and hips. Knowing the person’s height allows for formulations of various lengths based on the Golden Mean and combined with established size parameters, a trouser or torso pattern can be drafted for an average human body.

H = full length of body; also the span of laterally outstretched arms, measured from finger-tip to finger-tip, is equal to the height of the body.

1/2 H = upper part of body (torso) or lower part of body (legs)

1/4 H = length of leg from ankle to knee and length from chin to navel

1/6 H = length of foot and length of forearm (measured from elbow to wrist)

1/8 H = length of head from crown to bottom of chin

1/10 H = height of face; also length of hand

Drafting By Height: Trousers (based on 8 heads per figure)

The theory based upon the Golden Mean can be used to determine drafting measurements from a given figure height of an average or off-proportioned body. You need the following measurements to draft a trouser pattern: height, waist and hips. The scale is one head equals 1/8 of the total height.


for a person who is 5 feet 8 inches tall, one head length is 8 ½”

5′ 8″ = 68″ 68″/8 = 8.5″

Rise is 1 head plus 1″ ease plus width of the waistband

eg. rise = 1/8 height + ease + waistband width

Inseam is 4 heads minus Y (amount taken off for width of trouser cuffs)

eg. inseam = 1/2 height – Y

Outseam is inseam plus rise, or

5 heads plus ease minus Y plus waistband width

eg. outseam = 5/8 height + ease – Y + waistband width


Given a height of 5 feet, 8 inches, trouser cuff width of 18″ and a waistband 1-1/2″ wide, then:

rise = 68/8 + 1 + 1.5 = 11

inseam = 68/8 – 2.5 = 31.5

outseam = 5/8 x 68 + 1 – 2.5 + 1.5 = 42.5

Table for Leg Reduction (Y amount)
