Check and trim

Formal dresses demand higher precision than casual wear. Our 5-step workflow is tailored to eliminate fitting issues and ensure your midi formal dresses look premium on every body type.

Step 1: Design & Technical Brief

Submit your tech pack, sketches, or a reference garment. Tell us the occasion – is it for corporate events, weddings, or evening galas? We then suggest the appropriate silhouette (sheath, A-line, fit-and-flare, or princess-seam). Our pattern makers adjust the midi length (typically 2–4 cm below the knee or mid-calf) based on your target demographic.

Step 2: Fabric & Interior Structure Development

Choose your main fabric and lining. This is critical for formal dresses – we test the shrinkage rate and drape coefficient of your chosen material. We also develop the interfacing (fusing) to ensure collars, facings, and waistbands lay perfectly flat without bubbling after dry cleaning.

Step 3: Prototype Sample – Fit & Movement Check

We sew 1–2 pieces using your actual selected fabrics. Our sample room pays special attention to:

  • Bust & waist dart positioning – no puckering or gaping
  • Vent and slit stability – hems stay even when walking
  • Back zipper insertion – completely invisible and smooth
  • Shoulder & armhole fit – no pulling when arms are raised
    Turnaround: 10–12 days. Revisions completed in 5 days.

Step 4: Bulk Production with Formal-Wear QC

After your final sign-off, we cut using single-ply or low-ply spreading (to protect delicate formal fabrics). Our dedicated formal line ensures:

  • Three in-line inspections – pre-sewing fabric check, mid-production seam check, final garment check
  • Tension calibration – adjusted for each fabric type to avoid skipped stitches on satin
  • 100% zipper and button pull test – no hardware failures
  • Third-party inspection available upon request (SGS / Intertek)

Step 5: Premium Packing & Global Logistics

We offer folded with tissue paper or hang-pack options to preserve the dress shape. Add your branded neck labels, size stickers, and custom carton markings. Ship FOB Ningbo, CIF, or DDP. We provide full documentation (commercial invoice, packing list, and HS code consultancy).
