Collar Stays

Collar stays, also called collar stiffeners, are used to keep shirt collar points straight and sharp by stopping them bending.

They slip in on the underside of the collar closest to the tie. Most shirts come with plastic ones - apart from pinned or button down shirts which do not need them. I recommend investing in some metal ones as they are less likely to bend, and the weight holds down the shirt better. If you are feeling flush, you can even get silver or gold collar stays. Some people use horn, baleen, mother of pearl, but these are too light and prone to breaking. Just remember to take them out before washing.
