They’re comfy. They last for years and years. They don’t require dry-cleaning or any other kind of special treatment. They’re perfect for a number of occasions, from a trip to the grocery store, to a walk in the park, to an evening at the pub, to a number of even semi-formal social occasions. They’re incredibly versatile, meaning they look good with pretty much everything, from t-shirts to smart blazers. In fact, you can’t imagine life without them at all.
