This weeks Hello! Magazine has exclusive photos of The Duchess of Cambridge and Prince George as they head to the Caribbean island of Mustique to holiday with the rest of the Middleton family.  The photo shows Kate looking happy and relaxed as she steps off the plane holding six-month-old George in her arms.

Kate looked casually chic in her Ralph Lauren 'Tori' Breton Striped Tee.  This long sleeved boatneck tee from the Ralph Lauren 2012 resort collection has sold out but you can shop similar styles here. 

Kate wore her trusty J Brand '811' skinny jeans (in stock).

On her feet were the MINT VELVET plimsolls (sold out).

She finished the outfit with Givenchy 'Obsedia' sunglasses (in stock).

There is also some interest in what Prince George was wearing.  It is believed his adorable little sun hat is by Zutano, an American kids wear company which has a boutique in London.

There are currently no suggestions for his white coverall, but here are some similar styles ...

The Duchess of Cambridge owns a few of their Blue Label pieces, including a Custom Riding jacket and turtleneck sweater dress. The good news is, both of these items are part of the sale, however they are no longer available in the colours she owns. Here are some Duchess-approved styles (prices reflect discount) ...

It's been a while since I've done a budget style challenge, and after I found an alternative for Catherine's turtleneck dress, I thought it would be an ideal outfit to repliKate.  
 
The Duchess of Cambridge wore this outfit back in December 2011 when she and Prince William visited the Centrepoint Camberwell Foyer facility.  She paired an olive Ralph Lauren Blue Label turtleneck dress with her trusty Aquatalia Rhumba boots and a simple Reiss black suede waist belt.  Kate completed the look with her Kiki McDonough Grace earrings. 
 
The estimated cost of Kate's outfit is US$2100! After a little internet shopping, I've managed to put together this entire look for about 10% of that value!  You can steal Kate's style for under US$220 :)

Popsugar have exclusive pics of the Duchess of Cambridge grocery shopping at her local Waitrose supermarket in Anglesey. This is the first time Kate has been publicly photographed since leaving the hospital with Prince George.  Kate looked casually chic in a nautical inspired ensemble, wearing a Ralph Lauren breton striped top, Topshop maternity MOTO black skinny jeans, Givenchy sunglasses and her comfy Sebago boat shoes.

Sold out - the Ralph Lauren Blue Label 'Tori' cotton jersey navy/cream stripe top is from their 2012 collection. The top was identified by Michelle Forest. Shop repliKate styles.

It was initially thought that Kate wore her Paige 'Skyline' jeans, but the current consensus is that Kate wore the Topshop Maternity MOTO Black Leigh jeans, which would be a more comfortable option given that it's only been 5 weeks since the birth of Prince George. Thanks to My Small Obsessions for the ID. Shop the Topshop MOTO denim collection ...

Kate completed her nautical ensemble with a comfy pair of taupe/white Sebago 'Bala' boat shoes.

Kate wore her hair in a pony-tail and positioned her trusty Givenchy sunglasses atop her head.

Kate's outfit has an estimated cost of US$550, but I've managed to repliKate the entire outfit for almost one ninth of that value, and all from Target!
