Joining up with Heidi's 
Inkling Explorations, here are a few descriptions of Marguerite Blakeney from 
The Scarlet Pimpernel.
  Marguerite Blakeney was then scarcely five-and-twenty, and her beauty was
      at its most dazzling stage. The large hat, with its undulating and waving
      plumes, threw a soft shadow across the classic brow with the aureole of
      auburn hair—free at the moment from any powder; the sweet, almost
      childlike mouth, the straight chiselled nose, round chin, and delicate
      throat, all seemed set off by the picturesque costume of the period. The
      rich blue velvet robe moulded in its every line the graceful contour of
      the figure, whilst one tiny hand held, with a dignity all its own, the
      tall stick adorned with a large bunch of ribbons which fashionable ladies
      of the period had taken to carrying recently.
  Lord Grenville took a hasty farewell of the ladies and slipped back into
      his box, where M. Chauvelin had sat through this ENTR'ACTE, with his
      eternal snuff-box in his hand, and with his keen pale eyes intently fixed
      upon a box opposite him, where, with much frou-frou of silken skirts, much
      laughter and general stir of curiosity amongst the audience, Marguerite
      Blakeney had just entered, accompanied by her husband, and looking
      divinely pretty beneath the wealth of her golden, reddish curls, slightly
      besprinkled with powder, and tied back at the nape of her graceful neck
      with a gigantic black bow. Always dressed in the very latest vagary of
      fashion, Marguerite alone among the ladies that night had discarded the
      crossover fichu and broad-lapelled over-dress, which had been in fashion
      for the last two or three years. She wore the short-waisted
      classical-shaped gown, which so soon was to become the approved mode in
      every country in Europe. It suited her graceful, regal figure to
      perfection, composed as it was of shimmering stuff which seemed a mass of
      rich gold embroidery.
  The moon had sunk low down behind a bank of clouds. In the east a soft
      grey light was beginning to chase away the heavy mantle of the night. He
      could only see her graceful outline now, the small queenly head, with its
      wealth of reddish golden curls, and the glittering gems forming the small,
      star-shaped, red flower which she wore as a diadem in her hair.
