Fashion shows in Paris tend to feel very serious. They're staged in the grandest Baroque buildings and they're very exclusive. On the night of the most serious, most exclusive show of Paris fashion week--Hedi Slimane's debut collection for Yves Saint Laurent--Olympia Le-Tan presented her spring summer ready-to-wear and handbag collection. It was not serious. It was not exclusive. It was pure fun. The most fun I had at a fashion show all week, in fact.
