> Replace a draft's content.

Source: https://docs.tryyoursize.com/reference/python/garments-update-draft/

*Method* · `tryyoursize`

Replace a draft's content. Published versions never change (409).

```python
def update_draft(garment_id: str, garment: GarmentInput) -> GarmentVersion
```

## Parameters

- **`garment_id`** (`str`, required): The draft's ID.
- **`garment`** (`GarmentInput`, required)
  - **`category`** (`GarmentCategory`, required): The garment type; it sets which POMs are needed.
  - **`fit_intent`** (`FitIntent`, required): The designer's intended silhouette; sets the ease targets the fit judgement compares against.
  - **`sizes`** (`string[]`, required): Size labels, smallest to largest.
  - **`poms`** (`POMTable`, required): Garment measurements per size: size label → POM code → millimetres. Widths are flat half-measurements. See GET /v1/studio/garment_dictionary for codes and plausible ranges.
  - **`grading`** (`GradingRule`, optional): How the POM table was derived: the base size's values plus, per POM, the increment (mm) between each pair of consecutive sizes (len = number of sizes - 1). The table stays the source of truth.
  - **`fabric`** (`Fabric`, required): What the tech pack / mill sheet says.
  - **`import_id`** (`string`, optional): Pattern import linked to this version (omit to unlink).
  - **`season`** (`string`, optional): Season tag, e.g. "SS27".
  - **`tolerances_mm`** (`TolerancesMM`, optional): Spec-sheet tolerance per POM code, ± mm (e.g. {"chest_width": 10}). Optional; the flat preview uses ±5 mm when a POM has none.
  - **`spec_source`** (`SpecSource`, optional): Where the POM table came from, kept for audit. Set by Studio's paste/import.

## Returns

`GarmentVersion`: The updated draft. Published versions never change (409).
