Spring Beauty 2010

THE LOOK Taylor Swift rocked a wash of sea blue shadow all the way up to the browbone.

WHY IT WORKS The shot of white shadow works as a highlighter to keep the star's look from feeling over-the-top.

SIMPLE TRICK “Always use more than one color, especially with blue. Try a compact like Ombre 5 Lumières in Riviera ($56, yslbeautyus.com) and start with the most intense color on the lashline, applying the lighter colors as you work your way up,” says Brooke.
