Her blouse is modest and sets a professional tone for the office. It does not have a plunging neckline, does not reveal her midriff, and does not contain words, slogans, or pictures that could offend her co-workers. This is a great example of a business casual outfit for women.
Her woman's pants look nice without being too form-fitting, and they aren't too casual like denim, spandex, or sweatpants might be.
She finishes her outfit with a great choice of conservative shoes. In a business casual office, athletic shoes and sneakers, loafers, clogs, leather boat shoes, and dress heels are acceptable. In warm weather, stockings aren't necessary for women. However, flip flops, sandals, slippers, or open-toed shoes are not appropriate for the workplace. Also, if you are a fan of footwear that is flashy and eye-catching, they should be worn on the street - not in the office. Even though the guidelines of a business casual environment can be somewhat lax at times, looking professional and conservative at all times is important.
