What garment type is specifically prohibited for licensees to wear while performing services?

The correct answer is that lingerie is specifically prohibited for licensees to wear while performing services. This regulation is primarily in place to maintain a professional appearance and uphold the dignity of the services being provided. Wearing lingerie can be seen as inappropriate or suggestive, which could create an uncomfortable environment for clients and potentially damage the reputation of the esthetician and the practice.

Professional guidelines in the esthetics field emphasize the importance of a polished and respectable presentation, which supports the notion of trust and safety between clients and practitioners. Additionally, regulatory bodies stipulate dress codes that prioritize both professionalism and hygiene in a salon or spa environment. By prohibiting lingerie, the regulations help ensure that all licensed estheticians present themselves in a manner that respects the nature of the services they offer and the diverse clientele they serve.
