How to choose work trousers that last

Work trousers get more wear than almost anything else you own. They’re sat in for hours, pressed against desks and car seats, and cleaned far more often than a jacket. That makes them the piece where quality shows fastest, and where knowing what to look for saves you from buying the same pair twice a year.

Cloth first

For trousers you’ll wear to work several times a week, wool is still the best material. It resists creasing, recovers its shape overnight on a hanger, breathes, and wears in rather than out.

Look for worsted wool, spun from long, combed fibres into a smooth, firm cloth that takes a sharp crease. Gabardine and wool twill are tight worsted weaves and especially hard-wearing. Flannel is woven from fuzzier woollen yarn. It’s softer and warmer, a good winter choice, but it doesn’t hold a crease for as long.

Labels often carry a “Super” number: Super 100s, 120s, 150s. It describes how fine the wool fibre is, not how good the cloth is. Very fine wools feel beautiful and drape well, but they’re more delicate and crease more easily. For trousers that will be worn hard, the lower end of the range is the more practical choice, and a firm, well-woven Super 100s will outlast a flimsy Super 150s.

Weight matters as well. Light “tropical” wools are good in warm offices and summer, mid-weight cloth works most of the year, and heavy cloths hang beautifully but are warm.

Stretch blends, wool or polyester with a few percent of elastane, are comfortable for long days, commuting and travel, and they forgive a lot. The trade-off: they don’t press quite as crisply, and a cheap polyester blend can look shiny under office lights. If you choose a blend, look for a high wool content.

The fit points that matter

Rise. A mid to high rise, sitting at or just below the navel, keeps a shirt tucked in and lets the trousers hang level. Low-rise trousers slip under the stomach, tilt forward, and the crease wanders off line.

Seat and thigh. You should be able to pinch a little cloth at the side of the thigh. Tight trousers wear through faster at the seat and the inner thigh, where the cloth rubs.

Leg. A gentle taper from the knee to the hem looks tidy. Too slim and the trousers ride up when you sit; too wide and they look borrowed.

Break. The break is the fold that forms where the hem meets the shoe.

• No break: the hem just touches the shoe. Crisp, and suited to slimmer cuts.
• Slight break: one small, soft fold at the front. The safest choice for work.
• Full break: a deeper fold. Traditional, best with wider trousers and heavier shoes.

Whichever you choose, the back of the hem is usually cut a little longer than the front, so it covers the top of the heel when you stand.

Look inside

Turn the trousers inside out in the shop. The inside tells you more than the label.

• Waistband. A curtained waistband has a strip of fabric hanging inside it, which helps keep a shirt tucked and stops the band rolling over.
• Back seam. Good trousers have a centre-back seam that runs up through the waistband, with spare fabric folded inside. That allowance lets a tailor let the waist out or take it in years later.
• Knee lining. A half lining at the front of the leg reduces wear at the knee and helps the cloth hang straight.
• Heel tape. A strip of tape inside the back of the hem protects the cloth from rubbing on your shoes.
• Stitching and fastenings. Bar tacks (short, dense stitches) at the pocket corners and the bottom of the fly, clean seam finishes, a zip that runs smoothly, and buttons sewn on firmly rather than flat.

None of these show from the outside. All of them show after a year.

Buy for the hips, alter the rest

Ready-made trousers rarely fit perfectly. Choose the pair that fits your hips and seat, and expect to pay a tailor to hem the legs and adjust the waist. Hemming and taking in a waist are simple jobs. Adding room in the thigh or changing the rise are not, so don’t buy a pair that’s wrong there and hope to fix it.

Care that makes them last

• Own at least two pairs and rotate them. Wool needs a day off to recover.
• Hang trousers by the hem from a clamp hanger, or fold them along the crease over a wide bar.
• Brush them after wearing to lift dust and lint.
• Steam out creases, or press through a damp cloth so the iron doesn’t leave a shine.
• Dry clean only when they’re actually dirty. Cleaning too often wears out the cloth faster than wearing it does.

Looked after like this, one pair of good wool trousers will outlast several cheaper ones, and look better all the way through.
