If you want a suit vest in blue, the Sheffield Riviera Trend Coastal Blues Check Suit Vest is a good place to start. Its pattern is a check that shows best up close.

It's cut to your measurements rather than a stock size.

It's made from 60% wool and 40% linen. Wool breathes, so you'll stay comfortable from morning into evening. The linen keeps it airy on warm days.

It works under the matching jacket at formal events and alone with a shirt and tie at relaxed ones. A white or light blue shirt keeps blue cloth crisp, and brown shoes warm it up. Bottom button open.

This suit vest works as the third piece of a suit or as its own layer. A suit vest, sometimes called a waistcoat, sits under your jacket or over a shirt on its own. 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.

You can get the Sheffield Riviera Trend Coastal Blues Check fabric as a blazer too.
