If businesses could succeed on enthusiasm alone, then Skaist-Taylor — the new “advanced contemporary” collection by Juicy Couture founders Pamela Skaist-Levy and Gela Nash-Taylor — should be an overwhelming success. It would be hard to find industry veterans more excited than these designers are. That unjaded energy was evident in their line, shown Sunday in their first-ever show held in a parking garage under Lincoln Center, where giant LED screens blared scenes from a redwood grove and a film starring Theodora Richards, who also walked the runway. Designed according to the duo’s genuine “California eccentric” whims, the clothes screamed West Coast with their combination of garish glamour and casual in one look. The fox fur worn with new renditions of those velour track pants that put Juicy on the map, complete with fedora and python stiletto booties, said it all. Whether it’s enough to stand out in a very crowded contemporary market remains to be seen, but we wouldn’t bet against it.
