Narrative:

We received a taxi clearance to runway 15R from bwi ground control. We were being marshaled out of the ramp area between gate xx and xy and given the all clear signal that our left wing had cleared aircraft air carrier Y and then waved out of the ramp area by the marshaller. He turned around and looked away from us towards aircraft air carrier Y. My first officer gave me a clear right response. I looked to my right to clear the area. We then proceeded to make a right turn to taxiway a to runway 15R. When we felt a bump, I stopped the aircraft, set the parking brake, looked to my left for the marshaller. He turned around when he heard the noise and then gave us the emergency stop signal. We shut down engines normally per the checklist and deplaned the passenger out the forward air stair door. Supplemental information from acn 390416: our crew had just arrived at our aircraft (aircraft #1) and was beginning to do the preflight. About then, we felt our aircraft move. Then while sitting in the first officer's seat, I looked up and saw the other aircraft (aircraft #2). Upon further inspection of the aircraft, we saw that the left wing of their aircraft had collided with the right wing of ours. I believed what caused the problem was that the aircraft were parked too close together.
