Step-by-Step Pattern Drafting
- Front Bodice (Asymmetrical): Trace a basic child’s front bodice block to the waist. Lower the left shoulder strap width to 3 cm while keeping the right shoulder at the standard 5.5 cm width. Draw a diagonal asymmetrical neckline sweeping from the right shoulder seam down to 4 cm below the canter-front waist on the left side. Transfer the bust dart into the side seam, then pivot and close the dart into the diagonal style line to create a smooth, contour-hugging moulded fit without puckering.
- Back Bodice: Trace the basic back bodice block. Mirror the right shoulder width to 5.5 cm and the left strap to 3 cm to match the front. Drop the back neckline into a gentle, matching asymmetrical scoop that finishes 2 cm higher than the front dip. Split the centre-back pattern piece into two halves to accommodate an invisible zipper closure.
- Front Skirt: Draft a half-circle skirt base with a waist radius calculated as Radius = frac Waist /3.14 = frac 58 /3.14 approx. 18.5 cm. Lengthen the left side hem by 12 cm to create a dramatic, sweeping asymmetrical high-low hemline that complements the bodice.
- Back Skirt: Draft a matching half-circle skirt base split into two symmetrical pieces for the centre-back zipper entry. Blend the back hemline smoothly from the shorter right side length (42 cm) down to the elongated left point (54 cm).
- Lining and Facings: Draft separate lining pieces for both front and back bodices using the main bodice blocks minus 0.5 cm at the armscyes and neckline edges to prevent roll-out. Cut self-fabric bias strips (4 cm wide) to bind the raw edges of the asymmetrical neckline.
- Seam Allowances: Add 1 cm to all side seams, shoulder seams, and skirt-to-bodice attachment seams. Add 1.5 cm to the centre-back zipper edges and 2 cm to the lower hem allowances.
Construction Instructions
- Step 1: Apply knit stay-tape along the bias-cut asymmetrical neckline and armhole edges of the front and back velvet bodices to prevent stretching during handling.
- Step 2: Stitch front and back bodice shoulder seams and side seams using a stretch stitch or narrow 3-step zigzag. Repeat for the lining pieces.
- Step 3: Place the bodice and lining right sides together along the neckline and armholes. Stitch along the edge, clip curves, understitch the seam allowance to the lining, and turn right-side out.
- Step 4: Insert the invisible zipper into the centre-back opening of the bodice and upper skirt, matching the waistline seam precisely.
- Step 5: Gather the upper raw edge of the front and back skirts to match the waist circumference of the finished bodice, then stitch the skirt to the bodice waistline.
- Step 6: Hem the asymmetrical skirt by turning under 1 cm twice and topstitching with a twin needle or a blind hem stitch.
Sewing Tips
- Nap Direction: Always layout all pattern pieces facing the exact same direction (with the velvet pile brushing downwards) so the garment has a uniform, rich colour shade under light.
- Pressing: Never press directly on the face of velvet. Use a needle-board (velvet board) or place a thick plush towel face-down underneath the fabric, and use a low-temperature steam iron hovering slightly above the surface.
- Needle Choice: Use a 70/10 or 75/11 stretch needle to glide cleanly through the knit backing without breaking fibres or causing skipped stitches.
- Feed Control: Reduce presser foot pressure slightly and use a walking foot or roller foot to prevent the stretchy velvet layers from shifting or sliding while stitching.
