Navy jacket, white shirt, fine. Add a flash of faded terracotta at the pocket and it's suddenly got a point of view. That's the Skytree in brick dust.
It's 100% silk in a 32 cm square, soft enough to puff without looking stiff and with a low sheen that suits a warm colour like this. It works especially well against blue, grey and cream, and it's just as good with a cord jacket as with a proper suit.
