The 23-year-old paired her classic black wraparound dress with an unusual fluffy pink bag in the shaped of a hammerhead shark, and some pale pink fluffy peep toe sandals.

The young socialite also added a burst of colour to her make-up look with a statement red lip, and deep purple nail varnish, a look she kept when she later attended the Ashley Williams show with Daisy Lowe and Laura Bailey.
Pixie was joined on Topshop's front row by Alexa Chung, who charmed the fashion pack with her dressed down yet chic outfit.
The 30-year-old teamed chose a long sleeved pale yellow top which she paired with a leopard print miniskirt, as well as some black and gold flats.
Alexa Chung was the epitome of Sunday chic on the front row
Alexa completed the look with a quirky pale pink Chanel handbag in the shape of a milk carton, from Karl Lagerfeld's supermarket-themed show in February.
The English beauty wore her hair in plaits which she tied with pale pink bows, and opted for a barely-there make-up look, finished off with nude lips.
The pair were spotted laughing and talking ahead of the show, before Cara Delevingne opened the catwalk show, soon followed by Lily Donaldson and Jourdan Dunn.
