The hair is unfortunate but the bold liner, without any other distractions on the face, is simple and effective.
I used Urban Decay 24/7 liner in flipside, a metallic turquoise, but Rimmel has a cobalt liner that looks promising as well. I’m wondering what other shades might serve this purpose; bright to the point of distraction yet not instantly editorial/theatrical like pink or yellow would be. Red, too, I think. But maybe not if the right shade?
Some stunning saturated violet, even lavender could work. Most shades of green are on the table. Gold…this calls for experimentation.
