Paul wrote to Timothy about many things. The church, the people, are individuals but must walk in the same direction if they want to be effective in their community. People outside the church watch and listen to see if what the church is saying or doing is true. So Paul writes about certain behavior in the church. It don’t know what prompted Paul to talk about modesty. But it is important that we as believers dress modestly. God never said we couldn’t be fashionable. He said modest. Apparently the women fashions were showing more body parts than God said was modest. Paul also addresses authority in the church and that no one is to usurp that authority. Today is an age of rebellion. I wonder if they went through the same thing. So Paul writes to Timothy to put the church back in order.
