Wearing a tie in a casual setting gives you some freedom in terms of how loosely you can wear it around your neck. For example, feel free to undo the top button of your shirt and leave your tie just tight enough to keep the collar in place. You can also leave the skinny part of the tie that is usually kept hidden behind the front of the tie out to hang loosely. However, this method isn’t easy to pull off as it can turn sloppy easily.
