Knee high boots are an Autumn classic so are a great investment. Gossip Girl's Blake Lively is often spotted rocking knee high boots, like this Rupert Sanderson pair and we love the way it looks. This seasons there are more boots than ever available and we're loving the classic black style. Sam Endelman's over the knee style (£188) would look great with thick tights and a skirt. Or how about Dune's ankle detail boots (£170) with a chunky heel. You can shop more knee high boots below.
