When we first saw these pictures of Olivia Palermo on the front row at the Giambattista Valli couture show in Paris, we naturally assumed she'd be wearing high fashion to match.
But we were pleased to discover that her gorgeous lemon yellow midi dress wasn't straight off a runway - it was in fact a well-disguised high street buy.
The City starlet donned this £46 frock from Topshop to the couture show, teamed with golden lace-up heels, layered statement necklaces, a clear clutch and skinny tan belt.
Go girl!
