Yes — collar stays are sold separately, and they’re easy to find
If the little plastic strips disappeared from your shirt collar in the wash, or you pulled them out and never saw them again, you’re not stuck. Collar stays are a standard accessory you can buy on their own, with no connection to any particular shirt. Men ask the question constantly — one common version online is simply, “can anyone recommend some collar stiffeners / stays?” — and the answer is straightforward. They’re widely available, often inexpensive, and a single good set outlasts dozens of shirts.
The confusion usually comes from how shirts ship. Most dress shirts arrive with thin, removable plastic stays already tucked into the collar pockets. Because they came with the shirt, they feel like part of it. They aren’t. They’re a consumable, and they’re meant to be replaced.
This guide covers what you’re actually buying, how to get the size right, and where to look. If you want the mechanics of sliding them in once they arrive, see our companion guide on where collar stays go.
What you’re buying: the basic types
Collar stays come in a few materials, and the price gap between them is real.
Plastic. The default. These are the strips your shirts came with — cheap, light, and disposable. A bag of replacements costs little. The downside is durability: thin plastic warps under a hot iron and snaps with repeated bending. Fine as a stopgap, frustrating as a permanent solution.
Metal. Usually stainless steel or brass. Heavier, rigid, and effectively permanent. Metal stays hold a collar point flatter and crisper than plastic, and they survive ironing and washing if you remember to remove them first. This is what most men mean when they ask about a buy-it-for-life set.
Magnetic. A two-piece system — a metal stay plus a small magnet that sits on the underside of the collar, holding the point down against the shirt. They solve the specific problem of a collar that flares away from the chest when you’re not wearing a tie. We cover them in detail in where to buy magnetic collar stays.
A recurring debate among men who care about this — “plastic or metal?” — usually lands on the same place: plastic to get by, metal once you’re tired of replacing plastic.
A couple of other distinctions you’ll see while shopping:
- Slot-in vs. magnetic. Slot-in stays simply stiffen the collar point. Magnetic stays add a small magnet that pins the point flat against your chest — useful if you wear collars open and they flare. More on those in where to buy magnetic collar stays.
- White or clear vs. metal-finish. White and clear plastic stays are meant to stay hidden inside the collar. The finish doesn’t show when the shirt is worn, so this is purely about the material you trust, not appearance.
- Single-size vs. mixed. Covered below, but it’s the choice that matters most.
Getting the size right
This is the one step people skip, and it’s the one that matters most. A stay that’s too short rattles around in the pocket and does nothing. One that’s too long won’t seat fully and pokes at the seam.
Collars aren’t all the same length, so collar stays come in sizes — typically measured in inches or millimeters along the diagonal of the collar point.
To find your size:
- Take a shirt whose collar you like.
- Slide the existing stay out, or feel for the pocket.
- Measure from the open end of the pocket to the closed seam at the point.
Most standard dress shirt collars fall between roughly 2.5 and 3 inches. Spread collars and larger shirts run longer; slim or shorter-point collars run shorter. If your shirts vary — and they probably do — buy a mixed-size set. Most quality sets ship with an assortment precisely because one man’s wardrobe rarely uses a single length. You match the stay to the collar instead of forcing one size everywhere.
When in doubt, size to the pocket, not the collar’s outer edge. The stay should sit fully inside with the rounded end seated against the seam.
Where to buy them
Collar stays are sold in more places than most people expect.
- Menswear and department stores. The shirt and accessories section, often near cufflinks and tie bars. Staff can usually point you to them even when they’re not on open display.
- Tailors and dry cleaners. Many keep basic plastic stays on hand and will sometimes hand you a few. A good tailor can also tell you what size your collars take.
- Online. The widest selection by far — plastic, metal, and magnetic sets, in single sizes or mixed assortments, at every price point. This is where you’ll find the buy-it-for-life metal and magnetic options that stores rarely stock.
You do not need to match a brand to your shirt. Collar stay pockets are close enough to standard that a good mixed-size set works across nearly everything in your closet.
What makes a set worth buying
A few things separate a set you’ll keep from one you’ll throw out:
- Material that lasts. Stainless steel or brass over thin plastic if you want them to survive ironing and time.
- The right sizes. A mixed-size set beats a single length unless every shirt you own has an identical collar.
- A smooth finish. Rounded ends and clean edges slide in without catching the collar fabric or wearing a hole in the pocket over time.
- Enough of them. Stays are small and easy to lose. Buy more than you think you need so a stray one in the laundry isn’t a crisis.
That last point is the quiet reason men end up buying stays more than once. The solution isn’t a better stay — it’s a habit. Our guide on where to store collar stays covers keeping a set somewhere you’ll actually find it.
The cost, honestly
This is a low-stakes purchase. Plastic replacements cost almost nothing. A solid metal set is still inexpensive relative to a single shirt, and you buy it once. Magnetic sets sit at the top of the range and are worth it specifically if you wear collars open, without a tie, and want the point to stay flat against your chest.
For most men, the smart move is to skip the cycle of replacing flimsy plastic and buy one good mixed-size metal set. It fits across your wardrobe, survives the wash if you remember to pull the stays first, and ends the question for good.
Do you even need to replace them?
One fair question before you buy: are collar stays necessary at all? It depends on the collar. Plain point and spread collars rely on them — without stays, the points curl and flare, especially when you wear the shirt open without a tie. Button-down collars, by contrast, fasten their points to the shirt with small buttons and don’t use stays at all. And soft casual collars often have no stay pockets to begin with.
So before replacing a missing set, check the shirt. If it has stay pockets, it was designed to be worn with stays, and a clean collar depends on them being there. If it’s a button-down or a soft casual collar, you may not need stays for that particular shirt. For the shirts that do take them, replacing the stays is the difference between a crisp collar and one that won’t sit right.
A collared shirt only looks pulled together when the collar does, and a couple of dollars’ worth of properly sized stays is the cheapest upgrade in menswear. For the bigger picture on how the collar reads in a business casual collared shirt, start with the pillar guide.
