Thank you for your feedback on the top button on your new shirts, and we're sorry you have had a little trouble in using said button easily. Due to the thicker material around the collar (due to increased wear/friction in that area) the button hole may well be a little tighter initially. Don't worry, however, as over time and with use, this will become looser and easier to use. After a month or two, you should find you're having no trouble whatsoever in easily using this button, just like all the others.
