The British beauty showed off her style credentials in a black long-sleeved mesh-effect and bandeau top combination, which she paired with cropped, flared white trousers. Accessorising with dazzling metallic statement jewellery, Alesha completed the look with black strappy heels, which included chainlink detailing on their block heels.
