Samantha Cameron took her second spin in this Jonathan Saunders Spring 2011 dress, when she had lunch with the Queen and Prince Philip back in June in London.

On the runway this pretty baby blue and white printed dress features a striped black and green waistband plus a sexy cut-out from the neck to the waist.

Samantha’s version of the dress doesn’t have this cut-out. Not surprisingly.

She kept the rest of her look ‘meeting the Queen’ appropriate by pairing her dress with simple black heels.

Tamsin Egerton wore the same dress to attend the Veuve Clicquot Gold Cup Polo Final last month.

The British actress wore the runway version of the dress with the super revealing cut-out but opted to wear the dress without the belt.

She accessorized her outfit with lilac Nicholas Kirkwood leather Moccasin-inspired pees-toes heels and a black quilted Chanel shoulder bag.

Whilst I prefer Tamsin’s cool accessories, the dress is definitely missing the runway belt and I think this makes the cut-out way too revealing so my vote is going to Samantha.

The pop of green colour from the belt really livens up her outfit despite the conservative modifications.
