Whether you wear your hair up or down, a hair accessory will give it added wow factor. The A-listers know this well, which is why hair accessories are often the must-have statement on the red carpet. Keep things simple with a ribbon like Charlize Theron or try Evan Rachel Woods subtly spiked hairband by Jennifer Behr. For a retro take, Dita does it best with a netted fascinator, while Petra Nemcova adds sparkle to her romantic curls with a jewelled clip. Alternatively, go all out with a large eye-catching number like Katy Perrys futuristic, oversized adornment or Nicole Richies bohemian beaded bando. Its the perfect way to turn heads this festive season.
