Take your cues from our model muses or channel a young Scarlett in Lost in Translation. To achieve a flushed effect bite your bottom lip whilst staring nonchalantly across the room, preferably whilst sipping an Old Fashioned or making eyes at the boy at the bar. Alternatively, scrub lips using a toothbrush to plump and smooth, then use RMS Beauty Lip2Cheek colour in Demure for a subtle pink tint.
For a bolder look, a deep rouge is always a good idea.
