Historical romance with a wife that does a scarf dance...

Hello there! I am looking for a book I read years ago. It is historical, set in the Highlands, and it revolves around a young woman whose husband has ignored her for years (perhaps they haven't seen each other since they were married, I can't recall). I do remember that she decides to pretend to be a servant, and follow his camp as they travel. An old lady in the camp helps her learn how to dance seductively to seduce her husband, and she wears a very sheer outfit. She seduces him without her knowing it's his wife, and then after that I can't recall what happens.

Any help would be amazing!!!

The Black Lyon by Jude Deveraux has a similar, if not identical scene.

Touchstone The Black Lyon

You are both amazing!!!!
