After passing through 10;000 feet the Captain and I noticed an unusual smell circulating through the crew cabin. We called the Flight Attendant and she confirmed that she could smell the scent through the cockpit door.  The smell was not dissipating so we decided to don oxygen masks and run the QRC/QRH. We [notified] ATC and the Captain notified the Flight Attendant; passengers; and company of the situation.  We received radar vectors for the return to field at ZZZZ on the ILS Approach.  The approach and landing was normal.
EMB-145 First Officer reported an unusual smell in the flight deck during initial climb resulting in a return to the departure airport.
