Hello!

THE COMPONENTS

Marine's styling tips

Marine is 1.70 meters tall and she sewed LE Blazer in size 38 for an oversized effect.
She also chose to line it, giving the blazer a flawless finish.

You can choose not to line it and instead finish the edges with bias tape, as suggested in the original version.

FURNITURES

- 1.70 meters of fabric (140 cm width)
- 0.80 meters of lining fabric (140 cm width)
- Fusible interfacing for the bottom of the blazer
- Bias tape (optional if not lining the blazer): 4 meters
- Matching sewing thread

FABRIC SUGGESTIONS

Cotton Linen Twill, Gabardine, Corduroy, and all medium to heavy weight fabrics.

HER FAVORITE FABRIC

I fell for the Bubble Corduroy fabric in the DREAMY TWILIGHT color for its softness and boyish look, especially in this olive green shade. I also love playing with contrasting linings, and the checkered Seersucker fabric enhances that preppy vibe.

STEP-BY-STEP GUIDE

Difficulty level: Intermediate

Don’t be afraid of the lining—once the collar is attached, you’ll have done the hardest part.
Follow the step-by-step guide and you'll have a piece with flawless finishes!
Sewing this variant involves modifying pattern pieces 1, 2, and 7. The diagrams will help guide you through this.
By creating pieces for the lining before assembly, Marine’s guidance will make the process easier.

MODIFY

/ 1 /

THE FRONT & BACK

For both pieces 1 and 2, widen the shoulders by 1.5 cm and lower the armhole by 2 cm.
Redraw the side seam following the size 40 measurements.
Reduce the height of LE Blazer by 6 cm.

/ 2 /

THE FACING

Reduce the height by 6 cm as shown on the diagram above.

CREATING THE LINING

You will need tracing paper or kraft paper, a ruler and a pencil.

/ 1 /

FRONT

Take the previously modified front pattern and remove the facing allowance (merge pieces 1 and 7).
Then, add 1 cm for the seam allowance and reduce the height by 5 cm down to the hem notch, adding 1 cm of seam allowance.
Cut this piece from your lining fabric, double (x2).

/ 2 /

BACK

Take the modified back pattern and remove the collar stand allowance (merge pieces 6 and 2).
Then, add 1 cm for the seam allowance at the neckline and reduce the height by 5 cm down to the hem notch, adding 1 cm of seam allowance.
Cut on the fold to avoid a center back seam.

ASSEMBLING THE BLAZER AND LINING

Follow the blazer assembly instructions, but do not finish or sew the side seams.
On the entire bottom edge of your main fabric, apply a 6 cm wide strip of fusible interfacing to the wrong side of the fabric along the entire bottom of the blazer.

Once the collar is attached and the facings are assembled, sew the shoulder seams of the lining, right sides together.

Place the lining against the blazer, right sides together. Pin the armholes in place and sew.

Once the armholes are sewn, press the seams towards the lining with an iron,
and then topstitch along the seam on the lining side, creating a narrow stitch.

Place the facings right sides together and sew them together.

Snip the seams and turn the facings right side out.
On the right side, sew the side seams of the blazer and the lining, which should be aligned, right sides together. Pin and sew.
On the wrong side, sew the bottom seam, pin it in place, and stitch, leaving an opening of a few centimeters (approximately 10 cm).

Cut the corners on the bias and turn the piece right side out.
Hand stitch the opening closed.
Press the entire garment.
