This sentence is therefore the topic sentence for the paragraph.
Topic sentences are often found at the beginning of paragraphs. But not all paragraphs begin with a clear topic sentence. Sometimes writers begin with specific supporting ideas and lead up to the main idea. In this case. the topic sentence is often found at the end of the paragraph. Here’s an example:
School is tough enough without having to worry about looking cool every single day. The less I have to decide first thing in the morning, the better. l can’t tell you how many mornings i look into my closet and just stare, unable to decide what to wear. I also wouldn’t mind not having to see guys wearing oversized jeans and shirts so huge they’d fit a sumo wrestler. And i certainly would welcome not seeing kids showing off designer-labeled clothes. To me, a dress code makes a lot of sense.
