As Passenger A boarded our flight; I asked her to please make sure that her mask was on over both her mouth and nose.  She did not comply.  Then while in the cabin during boarding; I noticed Passenger A was still not wearing her mask properly.  I again asked for her to please fix it as it was required.  She informed me that her mask was too large.  I then went and retrieved a mask from the inflight kit and brought it to her.  Passenger A told me that she did not want our mask and that she was not going to change it...I gave her our required paperwork; informed the Captain and asked the gate agent to speak with her.  We decided to continue with her on our flight.  In flight; she was asked multiple times to comply with our policy again to no avail.  I asked for a Supervisor to meet the aircraft.  The Customer Service supervisors met the flight.  Passenger A continued to disregard the safety of everyone on board.
Flight Attendant reported a passenger would not comply with face mask policy.
