The Fashion for Less range will be made up of 90 options across three colourways.
M&S head of lingerie design Soozie Jenkinson told Drapers that elements of the range would go into all M&S stores from mid January and that some sleepwear would be introduced later in the season.
She said: “It’s a significant buy for us. Our prices have been getting keener but this range brings great price and fashion together in a younger, more fun way. There is a lot of print in this collection, and we are finding that print is now becoming more important across all our ranges.”
Jenkinson added that a quarter of M&S bra sales were now in size D and above and that the retailer was trialling J cups in its Truly You lingerie sub-brand.
