There are several ways to add custom fields:

**1. Via attributes (simplest)**
- Create attribute group "Specifications"
- Add attributes: Size chart, Composition, Country
- Assign to products

**2. Via module (more flexible)**

```php
// Add columns to oc_product table
ALTER TABLE oc_product 
  ADD size_chart TEXT,
  ADD material VARCHAR(255),
  ADD country_id INT;
```

**3. Via Events for display**

```php
public function eventProductView(&$route, &$data): void {
    $data['custom_fields'] = $this->getCustomFields($data['product_id']);
}
```

Recommend trying attributes first - it's the least invasive approach.
