I get it, but let's poke holes anyway. First, do you speak Latin? How are you going to understand what anyone says? Second, the Romans were vicious. You show up wearing weird clothes and unable to speak Latin they're going to do one of three things. One, they kill you. The most likely option, they did this alot and usually without bothering to ask first. Two, they make you a slave, and you get sent to work in the mines or on roads till you die, also something they did alot. Three, they arrest you, throw you in prison, torture you, and then kill you. Now let's go best case but unusual scenario. Someone realizes how different your clothing is and wants to know why. You can't speak Latin so they cut off your foot or a hand and throw you in jail. Assuming you live and don't die of infection they will torture you until you learn enough Latin to answer questions. At this point you may end up a slave anyways but now you know Latin and someone else also realizes you know things they don't.
Exorcizamus te, omnis immundus spiritus
omnis satanica potestas, omnis incursio
infernamlis adversarii, omnis legio,
omnis congregatio et secta diabolica.
Ergo draco maledicte
et omnis legio diabolica
adjuramus te.
Cessa decipere humanas creaturas,
eisque aetemae Perditoonis venenum propinare.
I could go on but it's too long.
