Frequently Asked Questions

Should you tuck in a shirt for business casual?

Yes, usually. If the shirt has a flat hem (straight across the bottom), it’s designed to be worn untucked. If it has a curved hem (longer in front and back), it’s designed to be tucked in. For business casual, err on the side of tucking — it looks cleaner and more professional.
