It depends on the office dress code and culture. In a more conservative environment, such as a law firm or bank, a leather skirt may not be appropriate. However, in creative industries like fashion or advertising, it could be acceptable if paired with professional attire such as a blouse and blazer.

Additionally, the length of the skirt is important to consider. A knee-length leather pencil skirt can look polished and sophisticated when styled correctly. On the other hand, a mini-skirt made of leather may be too risqué for most workplaces.

Ultimately, it's best to err on the side of caution when dressing for work and choose pieces that are professional yet still reflect your personal style.
