Low-calorie chocolate bar Kit Kat Senses will be revamped with a more female-friendly pack design from next month, to build on the £30m sales Senses has driven since its launch by Nestlé two years ago.

The on-pack image of the bar has been replaced with swirling gold curlicues, a brighter Senses logo and a 'creamy hazelnut praline' descriptor. It will benefit from a £2m package for the Senses brand this year.
