Our Madison Slate Blue Sharkskin Suit Vest uses a wool fabric. Look closely and you'll see sharkskin, a tight weave that shifts slightly in the light.

You can wear the vest with the matching jacket or by itself with your sleeves rolled. A vest gives an outfit more structure through your middle.

It works under the matching jacket at formal events and alone with a shirt and tie at relaxed ones. Burgundy and dark green ties both sit well against slate blue. The classic rule is to leave the bottom button undone, which lets the vest sit flat when you sit down and keeps it from riding up.

Your measurements set the cut, so it's made for your build.

Bottom button open. Fiber content is 100% wool. Wool breathes, so you'll stay comfortable through a long day. Give it a day off between wears so the wool can recover.
