Lady thought to be Arabella Stuart by William Larkin (Bonham's - London UK)
From www.liveinternet.ru/journalshowcomments.php.
Lady Arabella Stuart wears a very décolleté dress with what appears to be her chemise turned out and over her bertha in this Larkin character study. Her bodice appears to be decorated with a pair of black panels. She may also be wearing false sleeves.
