It is less presentational than Informal but not as loose, and potentially sexually suggestive, as full casual dress. Loafers or cap toe shoes. Sandals may also be appropriate in warm weather. Dark socks are still considered de rigueur for men. Women are given more leniency to wear light colored stockings, especially in warm weather. A button-down dress shirt, sweater, polo shirt, or sweater vest. Again, women are given more leniency, and are often allowed to wear a T-shirt if it is of a luxurious material.
