Definition Fichu: Triangular piece of lace, muslin, or other cloth worn about the neck and cleavage to fill in a low bodice or neckline and preserve a lady’s modesty. From the French ‘thrown over’. The Bridgerton family and Jane Austen and her female family and friends would have worn a Fichu over a light muslin dress for both warmth and modesty.
