OLYMPIAN JUMP: London Fashion Week is losing another big name this season — and this time the Olympics are to blame. After creating all the outfits for the opening and closing ceremonies in Athens — more than 6,000 — London-based designer Sophia Kokosalaki is pooped — and behind schedule with her spring collection. As a result, she will be showing in Paris rather than London. “She hasn’t had time to get her collection together yet for the London shows,” said a spokeswoman for the designer. As for the future, she added, “We’re not saying that Sophia will definitely return to London next season — we’ll see how it goes in Paris.”
