sizes property

The size of the product.

To represent different size systems or size types, consider using this format: [[[size_system:]size_type:]size_value]. For example, in "US:MENS:M", "US" represents size system; "MENS" represents size type; "M" represents size value. In "GIRLS:27", size system is empty; "GIRLS" represents size type; "27" represents size value. In "32 inches", both size system and size type are empty, while size value is "32 inches". A maximum of 20 values are allowed per Product. Each value must be a UTF-8 encoded string with a length limit of 128 characters. Otherwise, an INVALID_ARGUMENT error is returned.
