Is this jumper warm enough for winter?

Yes for most mild winters, especially layered under a coat. The 48% wool content gives it more warmth than a cotton or acrylic knit, but it is not a heavy outdoor sweater.

Wool-blend knits can pill where fabric rubs, such as under the arms and at the cuffs. Wash it inside out by hand and use a fabric comb to keep it neat.

How does it compare with a pure cashmere jumper?

It is more structured and holds its shape better, but it is less soft and lighter on cashmere. Pure cashmere feels softer and pills differently, while this blend is more hard-wearing.

What sizes does it come in?

Reiss sizes this style in its standard women's range, with the listed option being Small. Check the Reiss size guide, as its sizing runs close to UK dress sizes.

Can I machine wash it?

No. The care instructions call for hand washing, so use cool water and a wool detergent, then dry flat to keep the shape.

It is a knit of about 48% wool and 7% cashmere, with the rest synthetic fibers for structure. The high collar and ribbed trims are part of the design.
