If you want a double-breasted blazer in red and navy, the Bower Royal Red on Navy Small Twill Stripe Double-Breasted Blazer is a strong pick. You get a stripe you'll notice from across a room across the whole piece.

It suits client lunches, dinners out and weekend events. With red and navy, black shoes look more formal and brown ones more relaxed.

Fiber content is 100% wool. Wool holds a press well and recovers after a day's wear.

Add a pocket square.

It's cut to your measurements rather than a stock size. This blazer stands alone, so you can mix it with the trousers you already own. Keep it fastened when you're on your feet, which is how a double-breasted cut should look. A blazer is the jacket you'll wear most, so pick one that works with the trousers you already own, like grey wool, tan chinos or dark denim. Add trousers in the matching Bower Royal Red on Navy Small Twill Stripe fabric to build out the look.
