I've cited Bobbi Brown's advice that the most flattering lip color is two shades deeper than one's natural lip color. I've repeated that advice because it works.
What if you want an even more natural looking lip color than the rose brown that was touted? I found my match in Laura Mercier Stickgloss in Pomegrante, which lauramercier.com describes as "yellow-red-brown." It mimics my natural lip color, but is a little deeper.
Laura Mercier Stickgloss in Pomegranate
When I purchased Laura Mercier Stickgloss in Pomegranate at Sephora, the saleswoman said that this lip color would be really beautiful on me. She was right.
