Miranda Kerr wore a swimsuit and a smile this afternoon when she hit the runway for Australian retailer David Jones in Sydney. She modeled a variety of outfits that will be available in its stores, including pieces from Aussie designers Collette Dinnigan, Camilla Franks, and Alex Perry. Her cutout one-piece was by the company Jets. Miranda changed into a white lace dress for the afterparty held at the city's Royal Hall of Industries. David Jones is keeping Miranda busy during her time Down Under between an in-store appearance and photo shoots. Today's catwalk appearance was Miranda's first since welcoming her son Flynn in January. Miranda said of her return to the runway in the Bond girl-esque suit, "I am a little nervous about getting back on the runway after just having a baby seven months ago in a swimsuit. But you know, I have been doing my squats, and I started Pilates as well as my usual yoga routine." Orlando Bloom watched Miranda prep for the show, but he wasn't able to stay for the actual event as he flew to New Zealand to start work on the next Lord of the Rings.
