Catherine, Duchess of Cambridge looks gorgeous in off-the-shoulder white knitted dress

The Duchess of Cambridge always puts her best fashion foot forward, but her latest look has taken effortless glamour to a whole new level.

You’d never guess the Duchess of Cambridge has had three children.

Kate Middleton has stepped out in London overnight wearing one of her most beautiful looks to date, a fitted cream knit dress by designer Barbara Casasola.

The 37-year-old wife of Prince William attended a charity dinner, hosted by Australian chef Skye Gyngell at her restaurant Spring, to give her support to Addiction Awareness Week.

The Duchess last wore the stunning $AU3000 off-the-shoulder gown in 2016, which features a pinstripe pattern and flared skirt.

Kate, who is the Patron of Action on Addiction, polished off her look with a sparkling pair of Jimmy Choo point toe pumps, valued at $AU970, a matching clutch and Kiki McDonough diamond hoop earrings, which are currently on sale for $AU6200.

She finished off her look with her signature bouncy blow-dry and natural glowy makeup.

It comes after the Duchess attended Trooping the Colour, the Queen’s annual birthday parade, last week with the rest of the royal family.

Accompanied by her husband and their three children, Prince George, Princess Charlotte and Prince Louis, Kate was glowing in a sorbet yellow Alexander McQueen dress and matching fascinator.

Meghan, Duchess of Sussex, made a brief return from maternity leave to attend the event, after giving birth to her son Archie Harrison last month.

The ceremony is one the most iconic royal parades, with more than 1400 soldiers, who had trained for months, 300 horses and 400 musicians, on display to honour the Queen.
