I was serving as First Officer when our winglet tip hit a fuel truck mirror that was next to the plane. Background - Prior to starting the engine the Captain and I discussed that this would be an engine start in place before movement as it was a power out gate as well as noting the fuel trucks position as we usually do in DC in similar situations where fuel trucks stay parked next to our aircraft and that coordination with the marshalers will take place. After engine start and the Captain giving clearance that we were ready for directions to the marshalers he looked/cleared left and I looked/cleared right and continued monitoring the right side of the plane making sure clearance with the fuel truck from my angle. As the marshallers signaled the Captain we started moving and after a few moments the Captain got my attention 'asking what's he was doing?' Referring to the lead marshaller as I looked briefly to the monitor the front from my side and saw the lead marshaler was bringing his hands down from an energetic motion and finally bringing his wand signal to an X I said 'stop' and the Captain said that as well. Turning my body back around and bringing my attention back to the back right side of the plane to the best angle I could see while stopping I did not notice we hit anything and it was only after a minute or 2 of being stopped I finally recognized that there was an extended mirror from the fuel truck that was touching the winglet. I also took note that the fuel truck was on and had a driver in it and that the door that was connected to the mirror was open which I do not remember being the case prior to movement so I'm not sure if he was moving the truck or opening the door at that moment. Once recognition the Captain and I discussed and notified correct personnel. Passengers were de-boarded.Potential movement of fuel truck or fueler opening of fuel truck door.  As well as a potential lapse of wing walker observation.
