Just zapped in on our style radar: Twenty8Twelve’s Brea leather jacket, signed by Sienna Miller herself, no less.

A crucial staple in the closets of the fashion conscious, the Brea jacket is uber versatile and an absolute life saver considering the temperamental weather we’ve been witnessing lately.

Adding a perfect dose of cool biker-chic edge to spring’s floaty floral dresses or toughening up this season’s brights, the Brea biker’s edgy ebonised leather and pure gorgeousness make it a fashion lust-have well worth the investment.

But there’s added kudos yet.

After recently appearing in Selfridges London, Sienna Miller has put pen to leather and signed a select few of her creations – giving you inimitable style cred and a reason to boast to your fashion friends – exclusively available to snap up at Selfridges.

But with strictly limited edition stock, it’s bound to fly of shelves. Hurry and get a piece of fashion history before the ink runs dry and shelves run empty!
