Many companies have instituted a business casual dress code, and invitations to business functions often suggest that guests should wear “business casual” clothing. However, the term is somewhat nebulous, and sometimes leads to widespread confusion. It is clearly different than business formal, which suggests a tailored suit and tie, but should not be confused with casual wear such as jeans and t-shirts either. A general rule of thumb for business casual is that the individual should be neatly dressed, well put together, and professional looking. If you are ever unclear on company policy about business casual dress, ask to see a dress code or talk to a supervisor about acceptable office wear.

For both men and women, clothing should have a good fit. Clothing should not be too tight or loose, and should not reveal cleavage, stomachs, lower backs, buttocks, or bare ankles. Minor tailoring may be needed to ensure a smooth fit for business casual clothing, but is well worth it to keep the dresser looking professional. In addition, clothing should be pressed and in good condition, meaning that it has no fading, holes, or dangling threads, and is also wrinkle-free.

Slacks such as khakis are acceptable, as are pants made from cotton, microfiber, and summer weight wool. Jeans and knits should be avoided. For women, all skirts should fall, at a minimum, to the knee, and should not reveal the thighs when sitting. Small slits to facilitate walking comfortably in long skirts are acceptable, but should not be designed to reveal the leg. In all cases, undergarments such as slips, undershirts, brassieres, and underwear should not be visible.

Tops such as button-down cottons and collared polo shirts are acceptable business casual wear for both genders, while women may also wear sweaters. T-shirts and apparel with logos are usually not considered appropriate for the office, unless the shirt is branded with the company name. Tank tops and cut-off shirts should be avoided, and short sleeved shirts should only be worn in warm weather or more casual office environments. A sport coat in subdued colors can be used for a slightly more dressy business casual look.

Accessories such as discreet jewelry are permitted, and women can certainly wear scarves, hose if they are wearing shorter skirts, and understated makeup. Many men and women prefer to wear ties with business casual attire, as a tie can always be removed if it seems too formal for the situation. If a belt is worn, it should be made from leather, and shoes should also be made from leather, with a low heel for women. Patterns and prints for business casual attire should be subdued if they are worn at all; subtle stripes are acceptable, while vibrant tropical patterns are not.
