Missing size attribute (apparel)

Apparel feeds require size on every product. Google rejects listings without it in apparel-targeted markets.

Often the feed exports color and pattern but skips size, or uses size_type alone without the size value.

1. Add the size attribute to every apparel variant.
2. Use standard size labels for the target country — 'M', 'L', '32W', '8 US', etc.
3. If your products are one-size-fits-all, use 'One Size'.
