Chloe should use formal, professional language in her memo to the manager of her division at a clothing company. The audience for the memo is a manager within her company, so she should avoid using colloquial or informal language. Instead, she should use clear and precise language that is appropriate for a business setting. This includes using proper grammar, punctuation, and sentence structure. She should also use technical terms and jargon specific to the clothing industry when necessary. It is also important to make sure the memo is well-organized and easy to follow, with clear headings and bullet points to highlight key information. Overall, the language used should be clear, concise and to the point, avoiding unnecessary details.
