According to our Capricorn friends, it really sucks having a birthday between Christmas and New Years. Sienna Miller doesn’t seem to mind too much, for she named her clothing line after her birthday, December 28th. The actress and trendsetter joined forces with her designer sister Savannah, who previously worked for Alexander McQueen and holds a degree from Central St. Martins. With intent to produce pieces that reflect Sienna’s free-spirited style and utilize Savannah’s technical expertise, Twenty8Twelve isn’t your typical celebrity line.

Glamorous yet laid-back dresses and tops are constructed of luxe silks, while fine knitwear is reasonably priced allowing everyone a piece of the pie. Unabashedly flirty bohemian looks are kept from being too precious by unfinished edges and shorter hems—and unlike other celebrity lines we can actually picture Sienna wearing her designs!
