Marks and Spencer have brought out a "cosy" aviator jacket that's perfect for autumn, and is very similar to a far more expensive design available at Whistles. Marksies' Faux Shearling Borg Lined Aviator Jacket has a "snug" borg lining - a sheepskin-like material that's very similar to shearling.This makes the jacket a perfect choice for colder days as winter approaches.The chocolate brown jacket is available in sizes 6-22, and is also available in black.The regular fit means it’s ideal for layering with chunky jumpers, and the asymmetric zip will help keep out the chill.The product hasn't been on sale for long, but already has seven rave reviews from happy customers.
