Meet fashion’s new power couple! Cara Delevingne and Sienna Miller showcase their Easter sunnies

Cara Delevingne is undoubtedly the world’s most famous model right now, regularly mixing with the movers and makers, stylists and shakers of the fashion world.

But her all-time BFF (Best Fashion Friend) and wifey’ Rita Ora may want to look away now – because Cara spent Easter weekend with trend titan Sienna Miller, no less!

Both clad in retro 1950s-style sunglasses, the duo cut a very fashionable picture as they feasted on oysters (and probably a few trends) over the Easter break.

Snoyster love in luncheon Sienna ate them all! Lezza!!!!’ wrote Cara, sharing a snap of the duo dressed in their hip sunnies.

Happy Easter from me and Sienna! Snoysters for life! X.’

Rabbit ears and carrots may have only been en vogue over the Easter weekend, but if Cara  and Sienna‘s picture says anything, it’s that retro shades are back with a vengeance this season. Hurrah!

Cara opted for a contrast brow cat eye style while Sienna (so hot right now) posed in hot pink Carrera shades

Oh, and wearing sunglasses indoors? Suddenly acceptable, apparently.

Quick! Get the girls’ retro sunglasses look here and here – while the sun still has his hat on!
