Both Altair and Ezio have been known to blend into a crowd whenever they want, but they haven't had the sort of feature base that Aveline will have in the upcoming title Assassin's Creed: Liberation.
Okay, Ezio has used disguises before, but a bard isn't as appealing as, say, a well-dressed lady. Aveline's Lady Persona will allow her to rub elbows with members of the high society. In this disguise, she'll be able to charm people or even bribe them. Unfortunately, she can't stash as much weaponry in this outfit, but certain accessories can be motified. The one tease posted in the PlayStation Blog on this matter is a "poison dart-shooting umbrella."
Aveline will also have the Slave Persona, which will allow her to seamlessly blend in with indentured servants and workers. While wearing this disguise, she will also be able to call on fellow workers for help, which will more than likely be very similar to how courtesans work in other Assassin's Creed titles. This is definitely a necessity, since this persona doesn't allow any weapons of any kind to be used.
The final persona will be the traditional Assassin Persona, which will be much like any of the other two assassins in the series. Enjoy the official screens for these personas, and get ready for the official release on October 30.
