## The Shopper Workflow

**Step 1 — Open the widget**
Shopper taps the VTS widget on a Shopify product page. No app download. Works in any mobile or desktop browser.

**Step 2 — Enter height and weight**
Basic inputs that provide a baseline for the AI measurement model.

**Step 3 — Take two photos**
Front-facing and side-facing photos in fitted clothing. Standard phone camera. Standard indoor lighting.

**Step 4 — AI analyses the photos**
Computer vision extracts 20+ body measurements in 15–20 seconds. Measurements include: chest, waist, hips, inseam, shoulder width, torso length, arm length, thigh circumference, neck circumference.

**Step 5 — Receive recommendation**
Shopper receives their exact size for that specific product, plus a colour-coded fit heatmap showing how the garment will feel zone by zone.

**Step 6 (optional) — Virtual try-on**
Generate a photorealistic image of themselves in the garment and share it to social media directly from the widget.
