* Individual Orders: Each religious order has its own set of rules and guidelines for dress and appearance. Some orders might be very strict about what their members can wear, while others might be more lenient.
* Focus on Modesty: Generally, the focus is on modesty and humility. Nuns typically choose simple, conservative clothing and avoid drawing attention to their appearance.
* Practicality: Some orders might encourage practicality. If wearing nail polish would interfere with work or religious practices (like foot washing during rituals), it might be discouraged.
To find out if a specific order has rules about toenails, you'd need to contact the order directly.
It's important to respect the traditions and choices of individual religious groups.
