PARIS — The Yves Saint Laurent woman is going on safari for spring, but, in her new clothes, she’ll be more comfortable hunting on the Upper East Side than in the jungle. Tom Ford is guiding the trip, and he created a sensual, stylish and very chic, urbane collection. The important motifs and looks included lots of leopard, graphic tribal patterns and racy little knits. Here, his distinctive take on the safari jacket, in chiffon, with a matching skirt.
