The Roomten Guide to Overcoats

The essential finishing piece for Autumn/Winter 2026

There are few garments that define autumn and winter style quite like a beautifully made overcoat.

A good coat does much more than keep out the cold. It completes an outfit, creates a strong silhouette and, when made properly, can remain part of your wardrobe for many years.

For Autumn/Winter 2026, we are seeing a welcome return to proper outerwear: longer lengths, strong but natural shoulders, substantial fabrics and classic coat designs interpreted in a more contemporary way.

At Roomten, we can create an overcoat around how you actually dress. That might mean a traditional Chesterfield worn over tailoring, an Ulster coat in a characterful Donegal tweed, a lightweight raincoat for commuting or a shorter car coat that works equally well with tailoring, knitwear and jeans.

Here are some of our favourite styles.

The Chesterfield Overcoat

The Chesterfield is perhaps the quintessential tailored overcoat. Clean, elegant and relatively understated, it is an excellent choice for someone looking for one coat that can work with both business and more formal clothing.

Single-Breasted Chesterfield

The single-breasted Chesterfield has a particularly clean appearance and is extremely versatile. Traditionally cut around knee length or slightly longer, it can feature notch lapels, flap or jetted pockets and a classic straight or gently shaped silhouette.

Navy and charcoal wool remain timeless choices, but for something a little different we like mid-grey, dark brown, camel and subtle herringbones.

Wear it over a suit during the week, or combine it with flannel trousers, knitwear and loafers or boots for a more relaxed look.

Double-Breasted Chesterfield

For greater presence, consider the double-breasted version. The overlapping front provides additional warmth while creating a stronger silhouette through the chest and shoulders. Peak lapels work particularly well and give the coat a more distinguished appearance.

A navy double-breasted coat is exceptionally versatile, while charcoal, brown herringbone and textured wool give the style a slightly softer feel. For Autumn/Winter 2026, we particularly like longer double-breasted coats with a comfortable rather than overly fitted silhouette.

The Ulster Coat

If the Chesterfield represents understated city tailoring, the Ulster is its more rugged country cousin. Traditionally substantial and generously proportioned, an Ulster coat is characterised by its broad lapels, double-breasted front and practical, weather-resistant origins.

It is a style that looks particularly good in cloth with texture and character. Think Donegal tweed, herringbone, heavy wool and traditional British or Irish-inspired coatings. Brown herringbone is one of our favourites. Olive, lovat, charcoal and oatmeal can also work beautifully.

The length is important. We prefer an Ulster to finish below the knee, giving the coat its distinctive sweeping silhouette while providing excellent protection in colder weather. Pair it with tailoring, flannel trousers or simply good denim and a substantial piece of knitwear.

The Covert Coat

Originally designed as a practical country coat, the Covert has evolved into one of menswear’s most versatile pieces of outerwear. It is usually shorter and slightly lighter than a traditional overcoat, making it particularly useful during the transition from autumn into winter.

Traditional details can include a fly front, notch lapels, ticket pocket and distinctive rows of stitching around the cuffs and hem. Classic covert cloth is hard-wearing and traditionally comes in earthy shades such as fawn, tan, olive and brown.

For a contemporary Roomten version, we can keep the traditional character while simplifying some of the detailing. It is a great coat for someone who moves between town and country and doesn’t always want the formality or length of a full Chesterfield.

The Pea Coat

The Pea coat brings a different character to an Autumn/Winter wardrobe. Originally associated with naval clothing, it is shorter, double-breasted and traditionally made from substantial wool. The wide collar and lapels give it a strong appearance, while its shorter length makes it particularly easy to wear casually.

Navy is the obvious classic, but charcoal, dark green, brown and textured wool can completely change the personality of the coat. Try one with jeans, cords or flannel trousers, a roll-neck jumper and boots. For made-to-measure, we can refine the proportions and length so that the coat feels sharp rather than bulky.

The Raincoat

British autumn and winter weather makes a good raincoat almost indispensable. But practical doesn’t have to mean boring. A tailored raincoat can be designed with the same attention to proportion and detail as an overcoat, but constructed from lighter technical or treated fabrics designed to cope with wet weather.

For 2026, rainwear is increasingly becoming part of the outfit rather than simply something thrown over it. We particularly like longer raincoats with clean lines, comfortable proportions and enough room to wear over a jacket. Navy, stone, olive and tobacco are timeless choices, although stronger colours can create a more contemporary statement.

The Waterproof Mac

Sometimes simplicity works best. A waterproof mac has a clean single-breasted front, minimal external detailing and a straightforward collar. The simplicity makes it incredibly versatile. It can be worn over a business suit without looking overly casual, yet works just as easily with jeans and knitwear at the weekend.

Fabric makes all the difference. Modern waterproof and water-resistant cloths allow us to create garments that feel considerably more refined than traditional synthetic rainwear. A concealed front gives an especially clean appearance, while details such as slanted pockets, a throat latch, removable lining or detachable warmer can increase its practicality.

For British weather, it is one of the most useful coats you can own.

The Car Coat

The car coat sits somewhere between a jacket and a traditional overcoat. Shorter than a Chesterfield and generally finishing around mid-thigh, it is easy to wear, practical and particularly good for someone who spends a lot of time driving.

Its simplicity is its strength. A clean single-breasted front, understated collar and well-positioned pockets create a coat that can work over a suit but looks equally natural with jeans, chinos or knitwear.

For autumn, cotton twill and weather-resistant fabrics work particularly well. For colder months, wool, cashmere blends and textured coatings transform the car coat into a warm winter option. It is perhaps one of the most versatile choices for the modern wardrobe.

The Field Coat

Choosing Your Overcoat Fabric

The style of the coat is only half the story. Fabric determines its warmth, weight, drape and ultimately much of its character.

• Wool — the classic overcoat cloth. Pure wool provides warmth, durability and excellent drape, from a refined city Chesterfield to a substantial country Ulster.
• Cashmere and wool/cashmere — cashmere gives exceptional softness and a luxurious handle, while a quality blend balances softness, warmth, durability and practicality.
• Herringbone — a subtle herringbone adds texture without making the coat difficult to coordinate. Grey feels urban; brown, olive and oatmeal create a softer country feel.
• Donegal tweed — its characteristic flecks and textured surface give a coat enormous depth and individuality, especially in Ulster, raglan and relaxed double-breasted styles.
• Covert cloth — dense, durable and traditionally designed for outdoor use, with earthy colours that combine easily with autumn tailoring.
• Gabardine — its tightly woven construction creates a smooth, clean appearance with useful protection for raincoats and transitional outerwear.
• Technical and waterproof fabrics — modern performance cloths can be shower-resistant, highly water-resistant or fully waterproof while retaining a sophisticated appearance.

The Details Make the Coat

Made-to-measure gives you the opportunity to create something considerably more personal than simply choosing a colour. The lapel can be notch or peak, narrow or broad. The coat can be single or double-breasted. Length can range from a shorter car coat to a sweeping below-the-knee Ulster.

Then there are pockets, buttons, linings, collars, vents and stitching. Horn buttons create a classic appearance. Dark buttons can keep things understated, while contrasting buttons give a more relaxed character.

A velvet collar can transform a Chesterfield. A throat latch adds practicality to a country coat. A removable warmer can turn an autumn raincoat into something that works deep into winter. These details allow us to create a coat specifically for the person who will wear it.

What Are We Wearing for Autumn/Winter 2026?

This season, we favour coats with a little more presence. Rather than very short, tightly fitted overcoats, consider a slightly longer and more relaxed silhouette that allows the fabric to drape properly and leaves enough room for layering underneath.

Texture is also important. Herringbone, Donegal, brushed wool and substantial tweeds bring interest to otherwise simple designs. Browns, tobacco, oatmeal, camel, olive and softer greys sit beautifully alongside the traditional navy and charcoal winter palette.

And don’t overlook rainwear. A well-cut waterproof mac or raincoat can be every bit as stylish as a wool overcoat – and considerably more useful when British autumn weather inevitably arrives.

Made to Measure at Roomten

An overcoat should be considered an investment. Unlike a fashion piece designed for a single season, a well-made Chesterfield, Ulster, Covert or Pea coat can be worn year after year.

At Roomten, your coat can be created around your measurements, your wardrobe and the way you intend to wear it. We consider not simply your body measurements but what will be worn underneath the coat. A coat intended primarily for suits needs to accommodate a tailored jacket comfortably. One designed for knitwear and casual clothing can be cut differently.

You can then choose the cloth, colour, weight, lining, buttons, pockets, lapels, length and finishing details. The result is an overcoat that is genuinely yours.

Frequently Asked Questions

What is the best overcoat to wear over a suit?

A single-breasted or double-breasted Chesterfield is an excellent choice. The coat should be cut with enough room through the shoulders, chest and sleeves to sit comfortably over a tailored jacket.

Should an overcoat finish above or below the knee?

It depends on the style. A car coat is traditionally shorter, while Chesterfield and Ulster coats can look particularly elegant at knee length or below. Your height and proportions should also influence the finished length.

What is the warmest fabric for an overcoat?

Substantial wool provides excellent warmth, while wool-and-cashmere and pure cashmere coatings can provide warmth with a particularly luxurious handle. Fabric weight, construction and lining are also important.

Can an overcoat be made to measure?

Yes. Made-to-measure is particularly beneficial for overcoats because allowances can be made for the clothing you intend to wear underneath, as well as your individual measurements and preferred silhouette.

What’s the difference between a raincoat and an overcoat?

An overcoat is primarily designed to provide warmth and is commonly made from wool or cashmere. A raincoat prioritises protection from wet weather and is usually made from treated cotton, gabardine or technical weather-resistant fabric.

Can I wear an overcoat casually?

Absolutely. An Ulster, Pea coat, car coat or textured Chesterfield can work extremely well with jeans, knitwear and boots. Choosing a textured cloth such as Donegal or herringbone can make a traditional overcoat feel considerably more relaxed.
