How can you make your button down shirts seem more casual?

 Well... there are a number of ways to do this.

1. Don't tuck in your shirt. You can also leave the first button or two undone. If you want to look "rough" and there are cufflinks you can undo the cufflinks too.

2. Do the "poofy" tuck. You can only tuck in the shirt at its ends and let the rest of the shirt go over the wastline. This is common in school band perfomances.

3. You can also just buy a casual button up shirt. This is not hard to find. If you like the show Two and a Half Men, Charlie wears these all of the time.

4. Get a casual button up shirt like in number three and unbutton it. make sure to wear an undershirt!!!!!!!
