A neckerchief is a small commitment. Sixty centimetres of silk, one knot, and a plain outfit suddenly looks like you thought about it. The Skytree in brick dust is the version that brings a bit of warmth with it, a faded terracotta red rather than anything loud.
It's pure silk, which is why it folds down thin and stays knotted rather than working itself loose. Wear it high and casual over a T-shirt, or open the collar and let it sit as a cravat.
