Three Gentleman Jack fans will soon be stepping out in Savile Row suits courtesy of a new off-trade promotion.

Bottles of the Tennessee whiskey part of the Jack Daniel's family of brands will be dressed in a cardboard ­cover that looks like a suit.

Consumers that enter a barcode from each bottle on the brand's website have the chance to win one of three suits by designer William Hunt, or one of the 100 runners-up prizes of a pair of branded cuff-links.

The promotion for the charcoal-mellowed whiskey brand rolls out from the end of this month.
