One of the beauty highlights of LFW S/S 2011 was certainly the glittery pouts.
The look was created by using a red benefit lipstick in shade colour Frenchedand then carefully dabbing glitter over the top!
Master the look by practising first, and experiment with different colours: think cerise pink and orange. You may also want to very lightly layer / dab a clear gloss over the finished look to stop the glitter wearing off during the day and night.
Another alternative would be to mix real glitter with clear lip gloss. (edible glitter would leak dye through the gloss whereas real glitter will simply mix in) Then paint it over your red lips to create the finished look.
