Alexa Chung just wore a full-length, emerald-green gown that could have come right out of Keira Knightley's Atonement wardrobe

Thanks to Caders tie neck detailing and on or off-the-shoulder puff sleeves, she is one truly versatile wardrobe addition that can be worn 4 different ways depending on your mood or occasion

Embellished with delicate yarn embroidery, brilliant stones, and sequins

The shimmering long formal dress smooths over the curves before opening in an alluring side slit and cascading to a dramatic floor length
