When business meetings, interviews, or lunch dates fill your calendar, you'll be glad you've got this timeless twill blazer in your closet. The softly structured silhouette, classic lapel collar, and one-button closure makes it easy to make a good first impression. And when it's time to flex from profesh polish to a more casual vibe? A touch of stretch makes the transition easier when your besties call for an after-hours meet-up. From Martha Stewart.
