Simply titled 'MW' the collection is set to feature everything from evening wear to outerwear, all capturing that signature Matthew Williamson main-line aesthetic, but at a fraction of the cost.
So think less high-octane red carpet pieces, more wearable cocktail-hour frocks - with a focus on quality fabrics and cuts - and aimed at a slightly younger, more urban audience. "It's for having fun in," explains the designer himself.
Our personal hero piece? We can't get enough of the simple-but-effective knotted black maxi dress.
"We are delighted to present Matthew Williamson's debut diffusion line collection MW Matthew Williamson," says Luisa De Paula, my-wardrobe.com Buying and Merchandising Director.
"The collection stays true to Matthew's signature design aesthetic, but at an accessible price point."
The range starts at £98 for a necklace, and goes up to £497 for a coat, and is available to buy online at my-wardrobe.com now.
