What are Collar Stays?
Last updated 2026-06-15
The collar stay is the most invisible yet impactful detail in a dress shirt. Without stays, collar points have a tendency to curl upward at the tips, bow outward from the shirt, or wrinkle under the pressure of a tie knot — creating a disheveled appearance that undermines even the finest shirt and suit combination. With properly sized stays inserted, the collar points maintain their intended shape from morning to evening, framing the face and tie with clean, consistent lines. Most dress shirts ship with inexpensive plastic stays that are functional but imperfect. They can warp over time, especially if the shirt is laundered without removing them first. Upgrading to metal collar stays — stainless steel, brass, or titanium — is one of the simplest and most cost-effective improvements a person can make to their shirt presentation. Metal stays are sturdier, maintain their shape indefinitely, and provide slightly more weight that helps the collar sit with greater authority. Collar stay sizing matters: the stay should be slightly shorter than the full length of the collar point pocket to avoid poking through the fabric at the collar tip. Most standard shirts accommodate stays between two-and-a-quarter and two-and-three-quarter inches, but collar designs vary. Magnetic collar stays are a popular upgrade — they include small magnets at the tips that interact with magnetized plackets or external magnets clipped beneath the shirt, pulling the collar points down with gentle magnetic force for an exceptionally flat, controlled collar. The key maintenance rule is to remove collar stays before laundering. Machine washing with stays inserted can warp plastic stays, bend metal stays, and stress the fabric of the collar point pockets. Returning the stays before wearing ensures a fresh, crisp collar every time. Keeping a small dish or tray specifically for collar stays prevents the common problem of losing them during laundry day.
Management consultant Priya discovered metal collar stays after a long-haul flight left her plastic stays warped and her collar curling upward during a crucial client presentation. She replaced every shirt's plastic stays with stainless steel versions and noticed an immediate difference — her collars maintained their shape through twelve-hour days, overnight flights, and back-to-back meetings. The twenty-dollar investment in a set of metal stays transformed eight shirts she already owned, making each one look noticeably sharper without any other change.

Questions, answered.
Should you remove collar stays before washing?
Always remove collar stays before washing, whether by hand or machine. Machine washing with stays inserted can warp plastic stays permanently, bend metal stays, damage the small pockets that hold them, and create stress points in the collar fabric. Store removed stays in a consistent location — a small dish, a dedicated compartment in a jewelry box, or even taped to the inside of the closet door — so they are easy to reinsert before wearing.
What size collar stays do you need?
Collar stays need to fit the collar point pockets of your specific shirts, which vary by brand and collar style. The most common sizes range from two-and-a-quarter to two-and-three-quarter inches. The stay should be slightly shorter than the full depth of the pocket — about a quarter inch shorter — to avoid pressing against and deforming the collar tip. If buying a universal set, choose a multi-size pack that includes three or four lengths and test each with your shirts to find the correct match for each collar design.
