According to manners-expert Emily Post, dressy casual attire includes a sport coat, slacks and a nice shirt for men and a dress, skirt or elegant pantsuit for women. For men, a polo shirt is acceptable, as is a dress shirt or an open-collared buttoned-down shirt. A tie is optional. A dressy pair of jeans along with an elegant shirt also is acceptable for women. For women, the choice of shirt or blouse often makes the difference in dressy casual attire. Choose a blouse that is made of a sophisticated material, rather than cotton, or pick one that has decorative embellishments to increase the dressy factor.
