This woman is wearing a comfortable and casual outfit, but, she still looks great. Her sweater is informal and relaxed, but, it's still modest and well-fitting. Keep in mind that although a casual workplace dress code
allows for informal clothing choices, you are expected to wear clothing that is in good condition, attractive, and appropriate for work. A casual blouse or sweater, like the one in this photo, paired with jeans, is a staple outfit in a casual dress code work environment.
