I have no idea what shirt stiffeners (or shirt “stifferners” as the Etsy description has it) are. Also known as “collar stays”, it sounds as if they’re something you stick in your collar to, er, stiffen it. Good for the groom/groomsmen/father of the bride then?
Sterling silver, they can be personalised with your own quote, phrase or poem or the dates and details of your wedding. By Chris Parry, they cost $69 a pair.
