Sources talk about generational clothing by omission. During the late Roman Republic our sources mention how the young fashionable men dressed in a more Greek style with shorter/tighter clothes and shaved body hair. From this we can understand that older Romans would have work more modest clothing, and been less meticulously groomed. This is also seen in how they presented themselves in art: Greek statues showed men with youthful angelic beauty and fitness, while Romans valued more accurate depictions of older men, connoting wisdom, with birthmarks and flaws etc.

As such, the youth going towards ideas of Greek aestheticism (kind of like British fashion being influenced by the French) would suggest that older people would stick to more traditional Roman clothing.
