Lilac is summer's most unlikely beauty trend, but it's catching on quicker than we'd expected!

Last year it was orange lippy, but this year's 'it colour' is lilac - the bolder, the better!

Lilac lips were seen on the catwalk at Todd Lynn, Modernist and Zac Posen and they work perfectly with this summer's bright pastels.

Fearless celebs are getting in on the trend and before you know it, you'll be cracking open the lilac lippy for your next party look!

Lady Gaga loves lilac and has taken her obsession even further recently with lilac hair and a lavender travelling teacup.

Get the Gaga look with some creamy lilac lippy and matching accessories.

Never one to shy away from a trend, Peaches Geldof rocks the lilac look and though she looks like she's caught hypothermia, at least she's bang on trend!
