Construction Instructions
- Step 1: Construct the upper bodice lining and attach the mandarin collar along the neckline, clipping curves for a smooth finish.
- Step 2: Stitch the side seams of the tunic down to the waist marker, leaving the lower side panels open to create the signature high-slit Ao Dai panels.
- Step 3: Carefully hem the high-slit edges with a narrow 1 cm double-folded hem to maintain crisp, clean lines along the hip drape.
- Step 4: Assemble the pull-on matching trousers with an enclosed elastic waistband and clean hem finishes.
- Step 5: Press the entire modern tunic and trousers suit using a low-heat setting with a pressing cloth to protect delicate brocade or silk textures.
Sewing Tips
- Needle Choice: Use a fine microtex 60/8 needle for silk-based fabrics or a stretch needle if working with stretch-satin blends.
- Reinforcing Slits: Pivot accurately at the top of the side-slit pivot point and reinforce with a small bar-tack stitch to prevent tearing under active child movement.
- Collar Shaping: Interface the mandarin collar with a lightweight woven fusible to ensure it stands upright comfortably against the neck without stiffness.
