Is this a tie for winter?

Can this work with a flannel suit in the winter?

It's listed as a silk, so I'm assuming it's one of the raw silks based on its appearance, which suggests summer wear. Can the "slubbiness" of a raw silk pass for wooliness in the winter or is this strictly a summer thing?

F/W. Don't know if it's raw silk, but it's made up to look like donegal.
