Avoid religious and political insignias in the form of rings, ties, or pins. Your watch should be simple, plain, and analog. Briefcases should be leather, preferably brown or beige, and as plain as possible. A cotton or linen handkerchief is recommended. Belts should match or complement your shoes and have a simple buckle.
Women have more room for creativity than men, which means they also have more room for mistakes.
Limit creativity to materials, patterns and cuts. Wool wrinkles quickly, so a cotton-synthetic blend may be best, particularly in warm climates. In addition to solids and pinstripes, various plaids may be acceptable. To be safe, wear something that falls just a little below the knee. Charcoal, medium gray, steel gray, black, and navy blue are good colors, all of which look good with a white blouse.
