John LewisSuper 100s Wool Sharkskin Regular Fit Suit Jacket, Airforce Blue, 38S

You've probably seen the phrase Super 100s a lot while shopping for suits. It's a measure of how fine the wool is, with a higher number translating to a finer wool which will feel softer and smoother to the hand. You can expect that fine feel from this THOUGHTFULLY DESIGNED suit jacket, along with the breathability that natural fibres like wool are known for.

The world has changed a lot in the last few years, and dress codes are no longer what they used to be. However, there are still plenty of occasions in life when only a sensible suit will do. Airforce blue is a well-considered choice for any event you could need a suit for — a sound base for professional settings, or a canvas for brighter ties and pocket squares on special occasions.

Just because this is a 'sensible' suit doesn't mean it's stuffy to wear. The pure wool cloth was chosen for all-day comfort, and it's fully lined in navy with a piano-facing lining (named for the effect of the lining curving around the internal pockets like the curve of a grand piano). The wool features a sharkskin finish — a subtle weave that adds an almost metallic finish to the cloth.

Matching suit waistcoat and trousers are available to complete the look.
