ILS XX into ZZZ. I was pilot flying; following the incorrect glideslope and got a low altitude alert from Pittsburgh Tower and recovered immediately. Complacency played a role on my part as well as the Captain who was Pilot monitoring. To prevent this from occurring in the future; I will open the approach plates regardless of weather conditions to ensure proper configuration.
C208 First Officer reported descending below the glideslope and receiving a low altitude alert from ATC.
