When considering your dress code, you must consider the office dress code. While you may be allowed to wear jeans or casual trousers in some progressive office settings, a business professional dress code requires a certain amount of formality. A blazer is a staple piece of business attire. You should wear a blazer if you are in a formal office, and keep a good rotation of blazer colors. You can experiment with a striped blue or white shirt, but keep your top colors simple. In general, button-down shirts are appropriate for office settings, as are fitted blouses. Avoid cufflinks unless the dress code specifically allows them.
If you plan on wearing a jacket, make sure it has at least six closed buttons. If you choose a jacket with single-row buttons, you might be considered too fashion-forward for business wear. A double-breasted jacket with a few closed buttons is acceptable, but a single row button is too much. A good rule of thumb is to avoid lace altogether.
Unless you are in a creative industry, lace is not appropriate for most offices. Usually, business professional dress codes require a suit and tie, but you can also wear a blouse or a skirt. For shoes, dress shoes are required, and business heels are acceptable for women. You can also opt to wear a blazer with a long jacket.
