What is the Latin phrase for a 'plain white toga of adult male citizens'?

The phrase "toga virilis" refers specifically to the plain white toga worn by adult male citizens in ancient Rome. This garment symbolized a citizen's coming of age and marked their transition from boyhood to adulthood and civic responsibility. The toga virilis was essentially a plain, unadorned garment that distinguished Roman citizens from others, particularly those who were not yet of age or who belonged to different social classes.

In contrast, the other choices represent different types of togas or garments with specific meanings or uses. "Toga pura" does not have a well-documented historical context as a standard term in Roman attire. "Toga candida" refers to the toga worn by candidates for office, which was whitened to signify purity and integrity. "Toga praetexta" is a toga that had a purple border and was traditionally worn by magistrates and young boys, indicating their status and rank in society. Each of these togas carries its own significance and connotations, while the toga virilis is distinctly recognized as the standard garment for adult male citizens.
