How to spot the original Flannel Overshirt

Washed cotton-rich flannel with a woven check in blue or brown that runs across the collar, pocket and cuffs, softly faded for a vintage look.

A single chest pocket on the left with a pointed flap and button, cut so the check lines up with the front of the shirt.

Dropped shoulders and a long, boxy body with a curved hem, roomy enough to wear open over a hoodie as a light jacket.

The overshirt

Soft washed flannel

Cotton-rich flannel is brushed for warmth and washed so it feels soft from the first wear.

The check is woven in, not printed, so it stays crisp and rich wash after wash.

A buttoned chest pocket and a neat collar keep it looking like a proper shirt.

Flannel is cotton that is brushed on the surface to raise the fibres, which traps a little warm air and gives the fabric its soft, cosy feel. Washing it before it reaches you softens it further and gently fades the check, so it looks like a shirt you have owned for years.

The fit

Generous, M to 2XL

A roomy fit with a 132 cm chest on the M up to 144 cm on the 2XL.

The length is 75.5 to 81.5 cm, long enough to wear loose over trousers.

Dropped shoulders leave room for a hoodie or a chunky knit underneath.

The generous cut means the overshirt does not cling. It hangs straight from the shoulders and looks relaxed whether you wear it buttoned or open. The longer length covers the waistband of your jeans and keeps your back warm when you bend down.

How to wear it

Blue or brown check

The blue check is fresh with grey, navy and white, and great with mid-blue jeans.

The brown check is warm with cream, olive and tan, a classic autumn combination.

Choose your colour and size above. Free UK delivery.

For a classic weekend look, wear the blue check open over a grey hoodie with dark jeans. The brown check is lovely with a cream jumper, olive trousers and boots. Measure a shirt you own and compare it with the chart to choose your size.

From Maria & Denis

A washed flannel check overshirt is the warm, relaxed shirt jacket that carries you through autumn and winter.

It is made from a cotton-rich flannel, washed for a soft, worn-in feel and a gently faded vintage look.

The cut is generous and boxy, with dropped shoulders, a classic collar and a single chest pocket.

It is roomy enough to wear open over a hoodie or a thick jumper, so it works as a light jacket on dry days.

Pair it with jeans and boots for the weekend, or over a plain tee with chinos for an easy everyday look.

The overshirt has become one of the most useful pieces in a man’s wardrobe, and flannel is its natural fabric. This one is washed for a soft, vintage feel and cut roomy enough to wear as an extra layer. On a mild autumn day it is your jacket; on a cold one it goes under your coat as a warm shirt.

Blue check or brown check, in sizes M to 2XL.

Fabric & care

Cotton blend, mostly cotton.

Machine wash at 30°C inside out, hang to dry.

Cotton is breathable and easy to care for: wash it at 30°C inside out with similar colours.

Hang it to dry rather than tumble drying, which keeps the colour fresh and stops shrinking.

A quick cool iron or a steamer smooths it out in seconds.
