Precision Fitting Process

Transforming a size S dress for a 2XL body using data-driven measurements and fabric physics

1. Original Garment Analysis

Garment Specifications (Size S):

  • Bust: 86cm (34")
  • Waist: 66cm (26")
  • Hip: 90cm (35.5")
  • Shoulder: 36cm (14")
  • Length: 142cm (56")

Fabric Properties:

  • Composition: 85% Polyester, 15% Spandex
  • Stretch: 25% horizontal, 15% vertical
  • Weight: 180g/m²
  • Drape Coefficient: 0.62

2. Target Body Profile (2XL)

Key Measurements:

  • Bust: 117cm (46") (+36% from S)
  • Waist: 102cm (40") (+55%)
  • Hip: 122cm (48") (+36%)
  • Shoulder: 43cm (17") (+19%)
  • Torso Length: 55cm (21.5") (+12%)

Body Shape Characteristics:

  • Apple shape (weight concentrated in midsection)
  • High waist prominence
  • Arm circumference: 38cm (15")

3. Data-Driven Transformation Process

Proportional Scaling

Calculate dimensional changes accounting for non-linear body proportions (e.g., waist expands 55% while shoulders only 19%)

waist_scale = (102-66)/66 = 0.55

shoulder_scale = (43-36)/36 = 0.19

Fabric Behavior Simulation

Model how sequins and sheer fabric will drape differently under increased tension points

drape_factor = 0.62 × (1 + (0.55×0.25))

sheer_tension = 180g/m² × 1.36

Structural Adjustments

Reinforce stress points and modify seam placements for the apple-shaped body type

new_seam_placement = original × 1.36

tension_dist = weight × area × gravity
