J'Adore this ultra snake print maxi from Zara's May 2011 lookbook. It's perfectly sensible for any summer's eve, strolling through the city or grabbing drinks and a movie with the girls. Just pair it with a chunky wedge and you're all set.
Bonus: The sexy slit allows it to transform easily from day to night.
Apparently Refinery 29 agrees with me on the snake print. Check out their current it list for the slithering serpentine style in stores now.
