A suit is often the most expensive sartorial investment you could make, therefore it’s economical to take proper care of it. And we all know the rule: dry-clean only when absolutely necessary and, even then, no more than once a year.

But what happens if you spill a glass of 1865 Chateau Lafite down the arm or get a little carried away with your lunch? Introducing the new machine-washable suit range from premium high street retailer Jaeger.

Once a phrase that would make traditionalists wince, the collection is a sleek line-up of single and double-breasted separates. Woven in Milan from 100 per cent luxury Italian wool in natty navy, rust and charcoal colourways, each piece is robust enough to endure a hard day’s (and evening’s) wear and still come up clean in a 30 wash.

Welcome to 21st century tailoring. Spills, falls and perspiration welcome.

Jaeger’s washable wool suit collection is available now in navy, with the remaining colours dropping online and in stores from August. Priced from £110 for trousers and £250 for jackets.
