sleeves from one's vest

The idiom "sleeves from one's vest" is an expression that is used to describe someone who is secretive, unwilling to reveal their true thoughts or intentions. The exact origin of this idiom is unclear, but it is believed to have emerged sometime in the late 19th century.

One theory suggests that the idiom "sleeves from one's vest" may have originated from the world of card playing. In some card games, players may hide cards in their vest or jacket sleeves in order to gain an unfair advantage over their opponents. This practice of hiding cards up one's sleeves is considered deceptive and dishonest. Over time, the idiom may have evolved to encompass a broader sense of secrecy and guardedness.

Another theory suggests that the origins of this idiom may be more literal, related to the practice of removing one's vest sleeves. In the 19th century, men commonly wore vests with detachable sleeves. Removing the sleeves could symbolize a shedding of one's outer layers, revealing a more vulnerable or hidden self. It is possible that this physical act became associated with a metaphorical sense of secrecy or concealment.

While the precise origins of the idiom "sleeves from one's vest" remain uncertain, it is clear that the expression is rooted in the idea of hidden intentions or concealed information. This idiom indicates a person who is unwilling to be forthcoming, preferring to keep their thoughts and motives veiled. The idiom is often used in contexts where someone is being evasive or ambiguous in their speech or actions.

When people use the idiom "sleeves from one's vest" to describe someone, they are suggesting that the person is keeping something hidden, much like a card player hiding cards up their sleeves. This implies that the person may have a secret plan or strategy, indicating a level of cunning or cleverness. Similar to having a "trick up one's sleeve," this idiom implies that the person is prepared to surprise or outwit others with their hidden knowledge or abilities.

On the other hand, if someone is said to have an "ace up their sleeve," it means they have a hidden advantage or resource that they can use at the right moment. This idiom originates from the practice of cheating in card games, where a player may secretly hold an ace card up their sleeve to use it strategically. In a broader sense, having an "ace up one's sleeve" implies that someone has a hidden asset or skill that they will use to their advantage when the time is right.
