The sample garment is sewn in lurex velvet, which is recommended because:

  • It is durable and stretchy.

  • It has a metallic appearance with a shimmering effect.

  • It works particularly well for body-fitted dresses and tops due to its flexibility and comfort.

Size Charts

Check the size charts and measure yourself to select the correct size, using the garment and body measurement tables in the guide.

Verify how much fabric you need by referencing the fabric yield table in the guide.

  • Ensure the grainline arrows remain parallel to the selvage.

Fabric Cutting and Preparation

Lay Out Your Pattern Pieces

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.

Cut Your Fabric

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.

Transfer Pattern Markings

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 0.9 cm (or 0.38 inch) seam allowance all around and 1.2 cm (or 0.5 inch) at the hem.

Step-by-Step Sewing Instructions

1. Create the Pleats

1a. Fold the pleats in a downward direction from one notch to another on both side seams of the front bodice.

1b. Secure each pleat in place using lock stitches.

1c. Press the pleats neatly to maintain their shape.

1d. Ensure all pleats are joined securely.

Repeat the same process for the three pleats on the shoulder.

2. Join the Shoulder Seam

Place the front bodice on top of the back bodice with right sides together. Align the shoulder seam and overlock along the seamline to attach the front and back pieces.

3. Finish the Hem, Neckline, and Armhole

Finish the hem, neckline, and armhole by folding the edge of the fabric twice toward the wrong side.

Top stitch along the folded edge, ensuring to secure the stitching with a backstitch at the end. Remember to tuck the fabric edge inside to prevent fraying.

4. Sew the Side Seams

Align the side seams of the front and back bodice with right sides together, then overlock both side seams.
