Where are neckties marked inside?

The correct answer is that neckties are marked inside in the neck loop. This area is typically where manufacturers place labels that may include information about the tie, such as the brand, fabric content, or care instructions. The neck loop is also an important part of a necktie's structure, providing reinforcement and helping to maintain the tie's shape when it is tied around the neck. This inner marking is less visible when the tie is worn, keeping the external appearance clean and aesthetic while still providing essential information as needed.

Other options, while they may refer to parts of the tie, do not typically carry manufacturer's markings. For instance, fabric could contain production details, but it is not standard for markings to be made directly on the fabric itself. The collar and the tip do not usually have any manufacturer labels; these areas are more concerned with the tie's finish or the way it is styled.
