Collar stays prevent your collar from curling up. This can happen if you are wearing a shirt that is not properly fitted or if you are moving around a lot during the day.
Collar stays add weight to your collar, which gives it a more structured and polished look.
How to use Collar stays Button the collar of your shirt. Lift up the collar and find the small slit at the bottom. Insert the collar stay into the slit with the narrow end first. Press the collar stay down until it is flush with the fabric. Repeat the previous steps for the other collar stay.
The collar stay should be long enough to reach the back of the collar, but not so long that it sticks out. The most common length for collar stays is 2.5 to 2.75 inches. However, the best length for you will depend on the size of your shirt collar.
Metal collar stays are more durable and will last longer. They are also more likely to keep your collar in place, especially if you are wearing a tie. Plastic collar stays are less expensive, but they are not as durable. They are also more likely to warp or break if they are not made of high-quality plastic.
If you are wearing a shirt with a button-down collar, make sure to button the collar before inserting the collar stays. This will help to keep the collar stays in place.
