"The King hath yesterday, in Council, declared his resolution of setting a fashion for clothes .... It will be a vest, I know not well how; but it is to teach the nobility thrift." [Pepys, "Diary," Oct. 8, 1666]
To be secretive and uncommunicative; keep one's counsel: So you had to play your cards very close to your chest/ Nominees have played their cards close to the vest
[1950s+; fr the practice of a careful cardplayer]
