Jessie J's style transformation is officially complete as she stepped out looking chic and sophisticated at GQ's Men's Collections party in London last night.
Hitting up the private dinner with Tinie Tempah – who went all out in a slick orange suit – Jessie opted for a casual approach to this season's sharp tailoring trend.
The head-to-toe black ensemble was created with a cropped tux jacket, skinny jeans and a pair of patent ankle boots.
Glossy tresses were then paired with natural, warm make-up to complete the gorgeous look.
