Si quis virgines appellasset, si tamen ancillari veste vestitas, minus peccare videtur: multo minus, si meretricia veste feminae, non matrum familiarum vestitae fuissent. si igitur non matronali habitu femina fuerit et quis eam appellavit vel ei comitem abduxit, iniuriarum non tenetur.
(Ulpian, Dig. 126.96.36.199)
If someone accosts respectable young girls, even though they are in slaves’ clothing, he is understood to commit a lesser offense: a much lesser offense, if the women were dressed as prostitutes and not as respectable women. Therefore, if a woman has not been wearing respectable clothing and someone has accosted her or abducted her compagnion, he is not liable to the action on outrage. (tr. Thomas A.J. McGinn)
