You've submitted a product that requires a value for the brand [brand] attribute, but have not yet submitted a valid brand. All products that fall into the Apparel & Accessories category require a valid brand.

For the apparel subcategories Shoes, Sunglasses, Handbags, and Watches, you must also submit a value for either the GTIN [gtin] or the MPN [mpn] attribute. If you submit the GTIN, it must be the one allocated by the manufacturer.

If you manufacture the product yourself, you may submit your store name as the value for the brand attribute. If the product doesn’t have a brand, submit the manufacturer or supplier name under the brand attribute.

For all apparel products that are targeted to Brazil, France, Germany, Japan, the UK, and the US, you must also submit values for the age group [age_group], color [color], gender [gender], and size [size] attributes.
