You're looking at the Sheffield Golden Leaf Dark Navy Twill Plain Double-Breasted Dinner Jacket, cut in wool blend cloth. The weave shows a twill with faint diagonal ribs.

Wear it to a formal dinner when you want to stand out a little. A white formal shirt and a black bow tie keep it right for black tie.

Double-breasted jackets look best closed, so plan to keep yours buttoned. Keep it fastened when you're on your feet, which is how a double-breasted cut should look. A dinner jacket in a patterned or colored cloth gives you a formal outfit that feels personal, which is why it's popular for holiday parties.

It's made to order from your measurements. Its composition is 95% wool and 5% cashmere. Wool lets creases fall out overnight on a hanger. Cashmere adds softness you'll feel the first time you put it on. Cashmere in the blend makes it a good fit for the cooler months.

Evenings suit it. Look for a tuxedo in the same Sheffield Golden Leaf Dark Navy Twill Plain cloth.
