You probably wouldn't recognize Michael Gambon without the signature robes and beard of Dumbledore, but the actor is a highly respected man of the theater who is the very image of Irish understated elegance. We could definitely all take tips from Dumbledore and mimic his cozyboy look, but if you ever want to look like a classy gentleman from the Continent who is breezing through life, take Gambon as your grown-man inspiration.
