Kate Bosworth shows off her VERY slim figure in denim pinafore dress as she stocks up on groceries with fiancé Michael Polish

With it being rather quiet on the movie front of late, Kate Bosworth has been making the most of her time with her fiancé Michael Polish, even if it is just a trip to the grocery store.

The super-slim actress dressed in impeccable style, as usual, wearing a denim buttoned-up pinafore dress with a black and gold high-waisted belt to give her slender frame the illusion of curves.

Walking in dark leather sandals and carrying a small matching bag, Kate, 30, never disappoints in the fashion stakes.

Her husband-to-be was less dressy, but still looked trendy in a grey long-sleeved T-shirt over another in white, with black jeans and retro Nike trainers.

 

Michael, 42, was sporting a shorter hairdo too, but still styled in his usual side-parting.

After attending the Fashion Week shows in New York and London, Kate will be awaiting the national release of her film collaboration with her director fiancé, Big Sur.

The second adaption in two years of a novel from the cult writer, the 30-year old actress plays Willamine ‘Billie’ Dabney the mistress of both Kerouac and his friend Neal Cassady.

The Beatnik writer is known for basing his stories on his own life experiences, and using the real names of his family and friends, but the characters in Big Sur are given pseudonyms due to publishers’ objections at the time.

However, in Polish’s movie, the real names of Jack Kerouac and his contemporaries are given to their respective characters.

After showing at this year's Sundance Film festival in Utah, the independent movie has yet to secure a mainstream cinematic release date.

Until that time, the couple can focus on wedding preparations, with the nuptials expected to take place later this year.

Not that Kate is going down the bridezilla route, as she told Allure magazine that she’s letting the organisation ‘organically unfold.’

‘The ceremony and all the other aspects are just kind of details. I feel married in every sense of the word, and I have for a long time.’
