CALLED M&S Collection Curve, the range is available in sizes 18-32 and includes everything from cotton basics to party dresses, and knitwear to coats, all designed to ensure a perfect fit for the curvier customer.
It's affordable too, with prices starting from £7.50 for a white T-shirt, going up to £89 for a black fitted dress.
During the design process, the retailer borrowed the expertise of popular plus-size fashion blogger Danielle Vanier, who says: "I have loved consulting on this collection with the team at M&S. It has been amazing working alongside a high-street retailer that I have grown up with, on this collection that really celebrates curves through every detail."
The 30-year-old, who has 94,000 followers on Instagram, also designed two dresses as part of the collection.
"For me, a little black dress is a must-have for any woman, and one of my favourite LBDs ever came from M&S," Danielle explains.
"I have taken a few elements of what I loved about this piece and created two new dresses for the collection. I have added some subtle sports details, like hardwear on the waist and mesh layering for a contemporary feel; so both can be styled in really different ways, whether you team with crisp white trainers for a chic take on daywear, or dress up with heels ready for the evening."
