Some people — many people — wear the same make-up all the time, just adding a bit more eye-blacking and lip-reddening for night. I’m not really one of them. Sometimes I pick a mood and a colour scheme, lay out materials and tools, shade and shape, and Ooh! there’s a dot of colour, and Pow! there’s a vamp-flick, and Bam! this is what’s known as smoulder.
