The wavy heart is a heart with movement built into its form - the edges ripple rather than curve cleanly, giving the shape organic energy that a standard heart silhouette does not have. Rachel Zoe executes this in two-tone base metal: a gold-tone heart body framed by a silver-tone outline, the contrast between the two finishes making the wavy edges read as a deliberate design choice rather than surface decoration. Butterfly back closure. A fashion-forward take on a motif that could easily read as conventional - the wave detail and two-tone execution give it the edge that keeps it current.
