We like the way Ursula chose to wear her denim shirt, mixing casual with luxury.
She's actually wearing Giuseppe Zanotti Design shoes (fall winter 2010/11 collection) and carrying a Bottega Veneta shoulder bag from the fall winter 2010/11 collection too.
You can shop a similar denim shirt, light-blue but with darker patch details, on Net-a-porter, the See by Chloé Patchwork denim shirt :
