The long sleeve tee is the layer that does the most and gets thought about the least. Here is how to buy a good one.
The long sleeve tee is the most worn garment in most wardrobes and the one people put the least thought into buying. It is worn alone in spring and fall, under everything in winter, and it is the first layer against you on more days than anything else.
Which means it is worth getting right, and getting it right is four things.
One: The Weight
The single biggest difference between long sleeve tees, and the one that decides what the garment is for.
Light. Thin and soft. A base layer. Disappears under a knit or a jacket with no bulk at all. Will cling and show everything if worn alone.
Mid. The standard. Can be worn alone or layered. Holds its shape and hangs away from the body. The one to buy first and the one to buy most of.
Heavy. Thick and structured. Worn alone, and it reads almost like a light sweatshirt. Too much bulk to go under most things.
If a listing gives a weight per square meter, mid is roughly 180 to 220. Below that is a base layer. Above that is outerwear-adjacent.
Two: The Cuff
The cuff is where a long sleeve tee fails first and where the cheap ones give themselves away.
A ribbed cuff holds the sleeve at the wrist and keeps the shape through washes. A plain hemmed cuff with no rib will stretch and bell out within a season, and it cannot be fixed.
Test it the same way you would test a sweater: pull the cuff gently and let go. It should come back immediately.
The cuff should reach the base of your thumb. Longer than that and it will be pushed up constantly, which is what stretches it. Shorter and it rides above the wrist when you reach forward.
Three: The Fit
The shoulder. Set-in, with the seam at the shoulder edge, reads as classic and layers best. Dropped, with the seam partway down the upper arm, reads as more current and adds bulk under a jacket.
The body. Should skim. If it shows the outline of what is under it, it is too close. If it hangs with no shape at all, it is too loose to layer under anything fitted.
The length. At or just below the waistband. Slightly longer is useful if you plan to layer it under a shorter top and show the hem, which is a deliberate look.
The neck. A ribbed crew neckline at the base of the neck. This is the other place a tee ages badly, and for the same reason as a sweater: pulling it on by the neckband.
Four: The Color
Plain and neutral if it is going to be a layer. White, black, gray marl, navy, khaki and sand all disappear under other things.
A horizontal stripe is the one pattern that works as a base layer, because it reads almost as a solid at a distance and still gives a plain outfit something to look at when worn alone.
A contrast panel, a print or a large graphic makes it the interesting piece, which is fine but changes what it is for.
The cuff is where a long sleeve tee fails first and where the cheap ones give themselves away.
The Four Ways One Gets Worn
On its own. Spring and fall, with any trouser. A mid or heavy weight in a plain color, and that is the outfit.
Under a short sleeve. A short sleeve tee or shirt over a long sleeve one. The contrast at the sleeve is the point, so either match the two colors closely or contrast them clearly. The short sleeve guide covers this combination.
Under a knit or a sweatshirt. The base layer. This is where a light weight earns its place, since there is no bulk. Let an inch of the sleeve and sometimes the hem show, which makes two plain garments read as an intentional outfit.
Under a jacket, alone. Mid weight, plain, and the jacket does the rest. A bomber over a plain long sleeve is about as simple as an outfit gets.
What Is a Henley?
A henley is a collarless pullover with a short buttoned placket at the neck, usually two to four buttons, made in the same fabrics as a long sleeve tee.
It sits between a plain tee and a collared shirt. The placket gives the neckline structure without a collar, which makes it read as slightly more considered than a plain crew without becoming formal.
The name comes from the rowing crews at Henley, who wore them as a uniform in the nineteenth century. The shape has barely changed since.
Worn with the buttons undone it is casual. Done up it is tidier. It layers under a knit or an overshirt exactly as a plain tee does, with the placket showing at the neck.
Long Sleeve Tee or Light Sweatshirt?
The line between the two is blurry and the difference is the fabric construction.
A tee is a single knitted jersey, smooth on both sides.
A sweatshirt is a fleece-backed knit, smooth on the face and brushed or looped inside. The crewneck guide covers the distinction in full.
In practice a heavy long sleeve tee and a light sweatshirt do the same job, and which word a brand uses tells you less than the weight does.
Caring for One
Wash cold and inside out. Warm water is what fades a black tee to gray within a season.
Never pull it on by the neckband. Both arms in, then pull down by the body.
Do not push the sleeves up habitually. It is the fastest way to stretch a cuff permanently, and once a cuff has gone the tee looks finished even if the rest of it is fine.
Hang to dry or tumble on low. Heat shrinks the length and the sleeve, and the sleeve is the measurement you can least afford to lose.
Fold rather than hang, particularly on heavier weights, which develop shoulder points on a hanger.
De-pill with a fabric shaver. Pilling is friction, not wear.
How Many to Own
More than you think, and they should be boring.
Three in mid weight, in white, black and gray marl, will cover almost everything. Add a navy and a sand if you want more, and one striped one for wearing alone.
These are the pieces where buying the same thing again when one wears out is the right answer rather than a failure of imagination. Browse the long-sleeve edit.
Long Sleeve Crews and Tees
Common Questions
What Is a Henley Tee?
A henley is a collarless pullover with a short buttoned placket at the neck, usually two to four buttons, made in the same fabrics as a plain tee. It sits between a T-shirt and a collared shirt, because the placket gives the neckline some structure without adding a collar. The name comes from the rowing crews at Henley, who wore them as a uniform in the nineteenth century. Worn with the buttons undone it is casual, and done up it reads tidier.
Can You Wear a T-Shirt for Smart Casual?
Usually yes, provided it is plain, a decent weight and in good condition. A mid weight tee in white, black or a neutral, with no graphics and an intact neckline, works under a knit or a jacket in most smart casual settings. What lets it down is a thin fabric that clings, a stretched neckband, visible pilling or a large print. If the setting is at the smarter end, a henley or a collared shirt is the safer choice, since both add structure at the neck.
The Short Version
Buy mid weight, check the cuff snaps back, and get the sleeve reaching the base of your thumb. Plain neutral colors if it is going under things, a stripe if it is going out alone. Wash cold, never pull it on by the neck, and stop pushing the sleeves up. Own more than you think. Browse the long-sleeve edit.
