While The Duchess of Cambridge's royal wardrobe regularly causes a fashion frenzy, it's not just royal fans who emulate her style, on occasion, celebrities do too.
On Friday morning Amanda Holden left the Heart Breakfast Radio Studios wearing a vintage-inspired blue polkadot dress that many 'Kate effect' fans may think looks rather familiar.
Cast your mind back to 2018, when the Duchess of Cambridge wore the sell-out Alessandra Rich polka-dot shirt dress with a contrast collar, which retailed for £1,225, for Prince Charles' 70th birthday portrait.
A year later, she re-wore the outfit when she visited an exhibition at Bletchley Park, England, to mark the 75th anniversary of the D-Day landings on 14 May 2019.
The elegant number was then replicated by numerous high street stores and sold out swiftly at every single one.
The Mathilde Navy & Cream Polka Dot Silk Tea Dress looks very similar to Kate's stylish number with its navy blue and white polka-dot print and contrast cream collar.
It also features long sleeves, and a slight puff sleeve, statement crystal buttons down the front and a pleat detail to the bust, with a flattering tailored waist.
This style comes in UK dress sizes 6 to 18 and costs £350, which is far less than the £1,000-plus original.
It has already sold out in numerous sizes over the last few months, but has just had a recent re-stock - so if you want to get the royal-approved look for less, now's your chance to do so.
