What did emperor Nero wear?

Answer 1

Nero wore what Roman emperors wore.

Emperors wore toga trabea or toga purpurea, a purple toga which only emperors were allowed to wear, on ceremonial occasions. Emperors also wore the toga picta, which also was purple, but, unlike all other togas, was also richly embroidered and decorated with gold. They wore them on special occasion. Officers of state who financed games could also wear this toga on the opening of the game and so did military commanders during a celebration of a triumph.

Given the expense of the above mentioned togas, ordinarily, emperors wore the Toga preatexta, a white toga with a broad purple border which was worn by the officers of state. What distinguished the emperor was that his toga was very expensive, made of finer cloth and worn more elaborately and that he wore a laurel wreath.
