Lost a hat in a taxi from Stillorgan to Ranelagh

Lost a ladies navy wooly hat in a taxi which took me from the leopardstown inn in Stillorgan to Ranelagh (we stopped at an atm in donnybrook) on the night of Mon 23rd Dec at about 12.30pm. The label on the hat is Parfois and I would love to get it back as it was brand new and I have a massive head and it is very hard to find a hat that fits!
