Margaret O'Leary, a master in knitwear, presents this season's must - have Breton sweater. With classic black and white stripes, long and wide sleeves, and stylish button detailing on the shoulder, it's incredibly versatile. You can dress it up for a fancy event or down for a casual day out, and it'll surely be your go - to top all the time.

To wear this sweater, simply slip it on over your head. It's great to pair with jeans for a casual look or a skirt for a more dressed - up style. When it comes to maintenance, it's best to hand - wash it in cold water to keep the colors vibrant and the fabric in good shape. Avoid using harsh detergents. After washing, lay it flat to dry. And don't iron it directly on the buttons to prevent damage.
