It looks like we'll be traveling under the sea for Spring 2012 — if the runways at Versace, Chanel, Jenny Packham, and Givenchy were any indication, the deep-sea fantasies from your childhood have been given a sexy, grown-up spin, and the results are pure magic. The trend isn't overdone with obvious fishtail hems or ripples of blue, but rather with clean, subtle nods to the ebbs and flows of the ocean — just see Jenny Packham's long, lithe silhouettes, Donatella Versace's seahorse-print separates, Givenchy's pretty pailettes, and the pearl-encrusted looks at Chanel (lest we forget Florence Welch performing in a giant clamshell on the runway). Not feeling all-over fish scales? You can still achieve the look in small doses with a pretty coral necklace, a delicate lace top, or layers of pearl chains.
