One of the most powerful weapons in a man’s sartorial arsenal, the blazer is that rare item of clothing which, when slipped on, has the ability to instantly alter how you look. Timeless, versatile and masculine, it brings a touch of sophistication to whatever you’re wearing it with – whether that’s a simple T-shirt and jeans combination or a pair of tailored shorts with an Oxford shirt.

With summer set to (hopefully) hit in earnest soon, a blazer will serve as the ideal outer layer, with this season’s stellar options ranging from the boldly coloured to the breezily lightweight.

These are the key styles you need to know, along with how to wear them:

The Striped Blazer

One of our 5 key pieces for spring/summer 2015, the striped blazer is having a moment and offers a welcome alternative to the ubiquitous checked styles that have started to dominate the industry.

Advocated by the likes of Gucci and Dior Homme on the SS15 runways, the high street has been quick to pick up the trend, with everything from block-stripe designs to traditional pinstripe options available on the current market.

That said, our favourites are crafted from lightweight seersucker or cotton, feature subtle ticking or bold regatta stripes, and come in a classic blue and white palette – timeless hues that will ensure your jacket gets good use for many more years to come.

Due to their boating heritage, both styles work well within nautical-inspired looks, so look to combine with maritime staples such as navy/white chinos, tailored shorts, boat shoes and Oxford shirts. Just steer clear of the Breton tee unless you’re a seasoned pattern mixer.

Perfect For: Those that want to introduce pattern to their tailoring collection.

Looks Best: In nautical-inspired and preppy outfits.

Key Brands: Zara, M&S, J.Crew, Uniqlo, Ralph Lauren, ASOS, Jack Wills, Hackett.
