A denim jacket at this time of year? Maybe not – unless it's the Lee Japan Stormrider winter denim jacket.
THe winter version of this classic, slimline denim jacket was launched way back in 1933 and is still being made for the Japanese market today, although very select UK retailers have stock too. As smart as any dry denim you'll find, it also has those seasonal additions of a blanket vlining and corduroy collar. Ok, it might not be great in sub-zero temperatures, but it should keep a chill out.
Available online, you can pick one up for £180.
