56. Couples who dress together
You probably didn’t notice that when Kate and William attend public events together, they try to match their outfits. You won’t find Prince William in pink, purple or yellow suits, but he matches either his tie, his pocket handkerchief or a pin on his jacket to accommodate whatever color his wife is wearing.

They say that a couple who dresses together stays together, and perhaps that’s their secret of success. For one of the Queen’s luxurious Garden Parties, Kate wore a pastel pink dress by one of her all-time favorite designers, Alexander McQueen, coupled with a matching headpiece, and to match her, William wore a pink pin on his lapel.
