Blazers are a wardrobe essential for the modern gent and have become the perfect match with jeans to make your outfit look that little bit less casual. Go for simple slim fit cuts where possible for a smarter look and avoid patterns if you're wearing over a graphic tee or shirt. Alternatively, make a statement with a velvet blazer or one with a leather-detailed lapel. Unless you're planning on dressing for Henley Regatta, avoid white at all costs or any with block stripes.
For a classic British heritage look, you can't go wrong with tweed and any blazer made from it will keep you warm during the colder months. Team up with your favourite pairs of brogues or Chelsea boots to complete the look.
