“A 1950s cocktail party in a Richard Neutra house in Palm Springs” was how Elie Tahari described his showroom presentation. And what a vibrant fete it was. This was creative director Ingo Wilts’ first spring season, and it was marked by amped-up colors, whether they were neon yellows and greens or vivid prints. To wit: a striking mix of tropical and animal motifs on an eyelet shiftdress and a green pythonlike pattern on a pair of slim pants worn with a pink shirt. Tahari also played with doilylike lace for dresses and skirts — a delicate touch to a summery lineup with much commercial appeal.
