Fabric Cutting and Preparation
Arrange the pattern pieces according to the cutting layout diagrams. Begin by positioning the pieces on the fabric, ensuring that the grainline arrow runs parallel to the selvage.
If you are using fabric shears, trace the pattern pieces and then cut them out, cutting away any pen, pencil, or chalk lines. Remember to cut out any notches that appear on the edges. These markings help line up the pieces when you assemble the garment.
Use your marking pen, pencil, or chalk to transfer the markings (such as circles, buttonholes, and fold lines) to the wrong side of the fabric. Mark the center front of pieces cut on the fold, as this will help you to align pieces accurately.
Seam Allowance
Please follow the seam allowances as indicated on the pattern file layers. These are provided specifically for each piece to ensure accurate construction.
This pattern uses a 1.1 cm (or 0.45 inch) seam allowance all around and 5 cm (or 2 inch) at the hem.
Step-by-Step Sewing Instructions
1. Create the Front Pleats
Match the two notches on both sides of the first pleat and press them together with right sides facing each other.
Repeat the same process for the second pleat.
Sew along the waistline to secure the pleats.
Repeat for the second front leg piece.
2. Sew the Darts
Fold each dart by matching the dart legs with right sides together.
Stitch along the dart line on the wrong side of the fabric and press the dart flat to one side.
Repeat for the remaining dart.
3. Construct the Fly Zipper Closure
3a. Fold the fly cover with right sides together and sew the fly shape on one side.
3b. Clip the seam allowance to help shape the fly cover. Turn it right side out and shape the curve.
3c. Place the fly piece onto the left front leg with right sides together and sew.
3d. Turn it to the wrong side and stitch along the edges to secure it.
3e. Place the zipper right sides together at the edge seam line and sew along the zipper tape away from the seam line.
3f. Position the open side of the fly cover onto the unstitched zipper tape on the wrong side.
3g. Turn the fly cover toward the front and sew along the fly cover seam line.
3h. Fold the fly seam allowance of the opposite front leg inward. Place it over the zipper and sew until the zipper end mark.
3i. Place the front pieces right sides together and sew a short seam from the zipper end notch to close the inner seam.
Place the back pieces right sides together and sew the crotch seam.
3j. Open the zipper and sew along the fly line from the top. Start at the zipper end and sew along the fly cover, leaving the fly cover free midway through the stitching.
4. Sew the Back Crotch Seam
Place both back pieces right sides together.
Sew along the crotch line.
5. Sew the Side Seams
Place the front and back pieces right sides together.
Sew the side seams.
6. Create the Belt Loops
Fold both sides of the belt loop strip inward.
Fold again and press to create creases.
Sew along both edges.
Cut five belt loops, each measuring 7.5 cm in length.
7. Prepare the Waistband
Apply fusible interfacing to the waistband, leaving the seam allowance free.
Press one side seam allowance inward.
8. Attach the Waistband and Belt Loops
8a. Pin the five belt loops at the center back, both side positions, and center front along the waistline.
Place the waistband onto the trousers with right sides together and pin evenly.
8b. Sew along the waistline seam.
8c. Close the waistband by folding the seam allowance inside and sewing along the edges.
8e. Push the seam allowance inside.
8f. Sew along the edges to fully close the waistband.
9. Sew the Inseams
Match the crotch ends of the front and back trouser legs with right sides together.
Sew the inseam continuously from one hem, through the crotch, and down to the opposite hem.
10. Finish the Hem
Use a hand needle to sew a blind hem stitch.
Alternatively, fold the seam allowance twice toward the inside and stitch from the front to finish the hem.
11. Add the Button and Buttonhole
Use a buttonhole presser foot to create a buttonhole approximately 1.5 cm away from the waistband edge.
Sew the button onto the right side of the waistband aligned with the buttonhole.
