You are not required to wear nylons or tights; however, you may wear them, especially in colder weather. Your nylons and tights should not attract attention. Choose nylons, no-show socks (for dress shoes), and tights in conservative, neutral colors. Avoid bright, colorful nylons or tights. Patterned nylons or tights should be subtle and simple in design and should not be made of any kind of mesh, fishnet, or lace material. If you wear knee-highs, make sure the tops do not show, even when sitting. Bobby socks are not professional or appropriate.
