ACID brights supply the party with an eye-catching pick-up this spring/summer 2011 and provide the perfect base for your Ibiza wardrobe. Inspired by the glow sticks and Happy Faces of the Nineties rave scene, this season's neon colour palette is paired with ladylike silhouettes to give the look a grown-up, modern twist.

Pleated pieces at Christofer Kane combined demure shapes with bold colours, while the longer lengths at Michael Kors lent these riotous hues an unexpected elegance.
