I love Frank & Eileen but several of my button down shirts and my Rory dress all are a little too low for my liking and I always think about taking to seamstress to have a button added. I came up with this easy, quick solution and you can place this faux button tack pin anywhere you wish. The tack pin is silver in color. The button is white iridescent, a 4-hole button, measuring 11mm /7/16”. This button does appear to be 1mm larger than the buttons on the shirts but it is very close. Please let me know if you have any questions. Thank you for looking. I am pictured in the Eileen denim in medium to help with size reference for button placement. You will receive one button attached to a tack pin with back.
