First, the bad. Mandy Moore is beautiful, as always, but her eyes are average-sized and her eyeliner does nothing to accentuate them. Her problem is that her black liquid liner is too thick and harsh which makes her eyes look smaller. A better idea would have been to make a thin line above the eyes and wing out the line slightly.
Now, the fabulous. Catherine Zeta Jones demonstrates that eye makeup can be subtle but not necessarily boring. She has subtle black liner all around her eyes while surrounding the liner, both top and bottom, with lavender shadow. The result is elegant but playful.
