You're looking at the Bower Royal Navy & Light Blue Mini Herringbone Stripe Double-Breasted Blazer, cut in wool cloth. There's herringbone, where the twill reverses to form a zigzag across the whole piece. Keep it closed.

This blazer stands alone, so you can mix it with the trousers you already own. It's built to stay buttoned, so the overlap sits flat when you stand. If you travel, a blazer is the one jacket worth packing, because it dresses up jeans for dinner and looks right over a shirt and tie for meetings.

Each one's made to order for the person wearing it.

It's a jacket for business casual days and smart evenings. You can't go far wrong with navy and light blue and a crisp white shirt. It's 100% wool, nothing else. Wool lets creases fall out overnight on a hanger.

If you'd like a matching piece, the Bower Royal Navy & Light Blue Mini Herringbone Stripe cloth also comes as a suit.
