Not many low costs out of Rome, though you can do Milan to "Paris" (Beauvais) for € 16.99 on Ryanair

With the low fares Easyjet charges you could also do Rome-London Stansted for €64 and then London Luton-Paris for €29

Though Air France does the flight for just €176 return.

Other options include taking the night train (around €150)
