Sienna Miller is a Burberry Prorsum Punk Princess at the Met Gala

Unless you’ve been living under a rock for the last 24 hours, you’ll know that the 2013 Met Gala took place in New York, last night, and that the theme this year was Punk: Chaos to Couture. Guests at the annual red carpet event rarely stick to the dress code, so I was excited to see how they approached the slightly daunting punk theme. I knew that whoever ended up wearing Burberry Prorsum would be safe, however, as Christopher Bailey works well with stud detailing. And Burberry’s guests – Sienna Miller and Cara Delevinge – did indeed look gorgeous on the red carpet.

Sienna Miller chose an open-back crêpe dress and a studded biker jacket for the occasion. She accessorised her look with silver hoop earrings and a spike-y headband, which she used to fasten her hair to the side, so it looked like she had an undercut. It’s one of my favourite hairstyles from the night, and you can recreate the look at home with this crystal and spike tiara from ASOS (£12). Follow Sienna’s lead and wear it with undone hair and a slick of kohl eyeliner.

And, rumour has it Sienna Miller and her fiancé, Tom Sturridge, will appear in the Fall 2013 Burberry ad campaign. So you may be seeing the 31-year-old actress in Burberry more often. After this red carpet appearance I hope the whispers are true!
