Assumptions (what the AI couldn't see)
- ◦Back styling inferred — not visible in the photo.
- ◦Fabric weight estimated from drape; confirm with a swatch.
- ◦Cap pouf comes from a cap slash/spread (≈1.3×), not from a body measurement.
- ◦Jabot fullness assumed ≈2× (soft cascade), cut on bias.
- ◦Collar band closes on a button; cuffs single-buttoned.
- ◦French seams assumed throughout for the sheer silk.
