A label on the reverse, in German, identifies the sitter as the consort of Ernst Friedrich of Saxe-Coburg-Gotha who was Princess Sophie Antoinette of Brunswick-Wolfenbüttel (1724-1802). However, the sitter bears a closer resemblance to her mother, Antoinette of Brunswick–Wolfenbüttel (1696-1762). Her clothes - a version of a wrapping gown arranged en déshabille – are more akin to portraits by Kneller of the late 17th and early 18th century, and her hair is high, echoing the high lace headdresses known as commodes at the start of the 18th century.

For a portrait of her daughter, Princess Sophie Antoinette, see RCIN 404648.
