A henley is a collarless top with a short buttoned placket at the neck — part T-shirt, part shirt, and more useful than either on the days between smart and casual. It takes its name from Henley-on-Thames, where the style was worn as rowing kit, but its modern life is simpler: it is the top a man reaches for when a T-shirt looks too plain and a shirt looks like too much. Here is what defines it, which version to buy, and how to wear it.
The defining details
Three things make a henley a henley:
- No collar. The neckline is a round or scoop neck finished with a band, not a collar — which is why it sits so comfortably under knitwear and jackets.
- A button placket. Typically two to four buttons running a short way down the chest. Worn fully buttoned it reads neat, nearly like a grandad collar; worn with the top button or two open, it is visibly relaxed. That small range is the garment's whole trick: one top, two registers.
- A soft fabric. Henleys are cut from jersey, ribbed knit or light woven cloth rather than stiff shirting. The version decides the season: fine jersey for layering, ribbed knit as a top in its own right.
The versions worth knowing
Our range is deliberately small — three, each doing a different job:
- The ribbed knit henley. The Kensington Ribbed Knit Henley (£59) is the substantial one: a ribbed knit that wears as a light jumper rather than an under-layer, in the autumn-to-spring weight that suits British weather most of the year.
- The long-sleeve jersey henley. The Stepney Long Sleeve Cotton Henley (£29) is the classic base: the layer under flannel shirts, overshirts and knitwear, and a clean long-sleeve top on its own in milder months.
- The short-sleeve henley. The Burnham Cotton-Linen Henley Shirt (£29) is the summer weight — a step up from a plain tee when trousers or chinos are doing the smart half of the outfit.
How to wear one
On its own
Long sleeves, top button open, with dark jeans or chinos and boots or clean trainers. This is the henley's home ground and the reason it survives every trend cycle: the placket gives a plain outfit one deliberate detail. The Kensington's ribbed knit carries this best — it has enough texture to hold the look alone.
Under knitwear
A henley's collarless neck makes it the easiest layer there is under a crew neck jumper: no collar fighting at the neck, no bulk at the chest, and the buttons give you temperature control through the day. Which knit goes over it is covered in our crew neck jumper guide.
Under an open shirt or overshirt
Stepney under a brushed cotton overshirt, buttons of the henley done up, shirt open: a layered, workwear-leaning outfit that suits weekends and relaxed offices. In a full cold-weather stack the henley sits at the base — the full order is in our winter layering guide.
What to avoid
A henley under a blazer rarely convinces — the neckline sits in an uncanny valley between T-shirt and shirt, and the T-shirt does the casual job more cleanly. And keep the placket honest: all buttons open is a beach look, not a pub one.
Henley vs polo vs grandad collar
- Polo: has a collar and reads sportier and smarter. Choose the polo when a collar is expected.
- Henley: no collar, button placket — more relaxed, better for layering.
- Grandad-collar shirt: a true shirt (woven cloth, full button front) with a band collar. The henley is its knitted, shorter-placket cousin; the grandad shirt is the dressier garment.
Both neighbours sit nearby in the catalogue — polos within knitwear, plain tees in men's T-shirts.
Fit
A henley should follow the body without clinging: the placket lying flat, not gaping, is the test. If the buttons strain, size up — a henley's ease is part of its look, and a tight one reads as underwear, which in fairness is where the style began its life.
The short version
Collarless, buttoned, soft — the henley is the considered alternative to a plain T-shirt and the easiest layering base in the wardrobe. Buy the ribbed knit for a top that stands alone (£59), the long-sleeve jersey for layering (£29).

Frequently asked questions
What is a henley shirt?
A collarless top with a short buttoned placket at the neck, cut from soft jersey or knit fabric. It sits between a T-shirt and a shirt in formality, and layers easily because there is no collar.
Should you button a henley?
Either way — that is the point of the placket. Fully buttoned reads neat; the top one or two buttons open reads relaxed. More than that is a holiday look.
What do you wear a henley with?
Dark jeans or chinos and boots on its own; under a crew neck jumper or an open overshirt as a layer. The Kensington ribbed knit (£59) is heavy enough to wear alone; the Stepney (£29) is the layering version.
Is a henley smart enough for work?
In a relaxed or smart-casual office, worn neat with chinos, yes for the knit version. Where a collar is expected, choose a polo or a shirt instead.
How much does a henley cost?
In our range, £29 for the long-sleeve cotton Stepney and the short-sleeve cotton-linen Burnham, £59 for the ribbed knit Kensington.
