After the Duchess of Cambridge found another wedding guest wearing the same outfit, we look at other style clashes
Kate Middleton rarely puts a foot wrong when it come to fashion but this weekend she accidentally committed the ultimate faux-pas.
At a society wedding in Marshfield, Gloucestershire she found herself wearing the same, £765, M Missoni tweed coat as another guest. Shock horror!
But in the battle of who wore it best, there really was no competition. It's embarrassing enough finding yourself in the same frock as someone else but when it's your ever-elegant, size eight future Queen... Ouch.
The Duchess isn't the only famous face to have experienced a fashion clash. We've found other celebs who have rocked up to an event seeing double.
Jamie King and Nicky Hilton
Model Jamie King and heiress Nicky Hilton found the funny side when they arrived at a fashion party in identical leopard print dresses back in 2011.
We love the way Jamie has dressed it down with minimal make-up and swept back hair. She's a clear winner for us.
Shakira and Pink
Singers Pink and Shakira were left red-faced when they arrived at the 2009 VMAs in the same black Balmain minidress.
It's a close call with this one but Shakira's thigh-high boots and tousled hair give her the edge and she gets our vote.
Amy Childs and Tricia Penrose
Actress Tricia Penrose gave TOWIE star Amy Childs a run for her money when they both arrived at the Pia Michi fashion show in the cutaway leopard print dress.
Both outfits are certainly eye-catching but 21 year-old Amy has got the edge.
Tina Fey and Sheryl Crow
Rocker Sheryl Crow and actress Tina Fey both chose D&G's floral prints for the Matrix Awards in NYC back in 2010.
Tina's halter-neck style is chic but Sheryl's clashing prints are considerably cooler.
And then there are the CopyKates - and the KateCopies. See which celerities copy the Duchess of Cambridge - and whose fashion footsteps she follows in.
