Her collection, Archive by Alexa, sees the fashion icon delving into the M&S archives, choosing her stand-out pieces which she has updated for 2016.
Each of the 31 pieces in the range has been carefully modernized with a contemporary colour palette and modern fabrics to make a collection which fully represents Chung's distinctive approach to style.
She said of the range: “I have always had an affection for Marks & Spencer. I am thrilled to be part of this special and unique project. There was something very touching about looking back through the British fashion and social history for which M&S is synonymous”.
This is the first of the "M&S &" series, which sees the company collaborate with a host of fashion influencers, including designers, style icons and brands.
The 31-piece M&S & Alexa Chung collection will debut in April 2016, and will be available in selected stores and online at www.marksandspencer.ie
