The garment accentuated Summer's lithe physique and came complete with a daring leg slit.
Summer added height to her frame with a pair of nude heels while she let her flame-haired locks fall loose down her shoulders for the evening.
Earlier in the evening, Summer stopped off at the Dorchester Hotel before making her way to the Pink London event.
Appearing in high spirits as she made her way into the hotel, Summer completed her look with a white, floral print clutch bag.

Her outing comes after Summer took to Instagram on Monday to share a post that read: 'There are two sides to every story, and then there are the screenshots.'
Although Summer did not reference who she was talking about, the redhead has been involved in a bitter dispute with the Bake Off host, 53, since they split two months ago.
MailOnline has contacted Summer and Paul's representatives for comment.
