Best Smart Trousers for the Office
The best smart trousers for most UK offices are the Bank stretch smart trousers (£59): a slim, flat-fronted trouser in a four-way stretch fabric that moves like a jogger on the commute and reads as tailoring at the desk. If your office runs smart-casual rather than formal, the alternative is the Putney slim tapered chinos (£59). Everything else is a dress-code question — so check that first.
The office pick: the Bank
The Bank is a slim men's smart trouser in four-way stretch fabric, with a flat front, belt loops, slant pockets and a buttoned back pocket. The stretch gives in every direction, which is what a working day actually asks of a trouser: stairs, trains, a chair for eight hours. The flat front and clean finish keep it on the tailoring side of the line — this is a trouser designed to be worn with a shirt, not a hoodie.
The smart-casual alternative: the Putney
Plenty of offices now run a notch below formal. There, a slim tapered chino does the job with less ceremony: the Putney has slanted front pockets, back welt pockets and a button-and-zip fly, in Stone, Navy or Black (W30–W38). Navy is the office-safe colour; stone is a summer and Friday pair. For more options across both registers, our best men's trousers guide compares ten styles by fit, fabric and price.
The honest dress-code caveat
If your office is genuinely formal — suit expected, clients in the room — neither a stretch trouser nor a chino is the answer; wear a tailored trouser. The Strand check tailored trousers (£83) are the formal end of our range. A comparison of our own range is what this is — not an independent market test — and the right pair is always the one your workplace's code allows.
What to check before you buy
- Fit through the leg: slim, not tight — you should be able to sit and climb stairs without the cloth pulling.
- A flat front for anything worn with a tucked shirt; pleats belong to a more traditional or more relaxed cut.
- Belt loops and a proper fly — drawstrings read as leisurewear however dark the colour.
- Length: a clean break over the shoe, neither pooling nor cropped, unless cropped is the deliberate look.

Frequently asked questions
Are stretch trousers smart enough for work?
Yes, if the finish is tailored: a flat front, belt loops and a clean leg read as smart trousers, and the stretch is invisible when worn. The Bank was cut on exactly that principle.
Can chinos be worn in a formal office?
Not where a formal dress code applies — the cotton cloth and casual pockets give them away. Chinos belong to smart-casual workplaces; formal offices call for smart or tailored trousers.
How many pairs of office trousers do you need?
Two pairs in rotation cover a working week comfortably with a third for travel or laundry days. One dark anchor pair (black, navy or charcoal) plus one alternate colour is the simplest wardrobe maths.
