Deep forest green behaves like a neutral once it's on. It's dark enough to sit quietly under a jacket, rich enough to be the only thing anyone notices about a plain shirt.
The Wenatchee comes as a 60 cm silk square, small enough to knot close at the neck without bulk. Pure silk means it slips into shape easily and holds it, whether you go for a loose twist above a T-shirt or a neater cravat at an open collar. Green like this gets on well with tan, cream, brown and grey, and looks especially good against denim.
